VI International Conference "Atomic and Molecular Pulsed Lasers"

September 15-19, 2003, Tomsk, Russia

The Sixth International Conference on Atomic and Molecular Pulsed Lasers (AMPL-03) was held in September 15-19 of 2003. Traditionally, it is held every two years in the ancient Siberian city of Tomsk. In the recent years, the AMPL Conference becomes increasingly popular, that is reflected in the number of papers presented and published in ten topical issues of Atmospheric and Oceanic Optics (1993. Vol. 6. No. 3; 1993. Vol. 6. No. 6; 1995. Vol. 8. No. 11; 1997. Vol. 10. No. 11; 1998. Vol. 11. No. 2-3; 2000. Vol. 13. No. 3; 2002. Vol. 15. No. 3; 2004. Vol. 17. No. 2-3) and four topical issues of Proceedings of SPIE 1995. V. 2619; 1997. V. 3403; 1999. V. 4071; 2001. V. 4747).
The last conference was devoted to the 40th anniversary of the start of the first laser in Tomsk and the 125th anniversary of the Tomsk State University.

The AMPL-03 scientific program was traditional and included the following sessions:
- gas and plasma lasers (Session A),
- metal vapor lasers (Session B),
- dye lasers and photoprocesses in complex organic molecules (Session C),
- physical processes in gas lasers (Session D),
- laser systems and their applications (Session E),
- noncoherent UV and VUV sources (Session F),
- laser output conversion (Session G).

The conference was supported by the Russian Academy of Sciences, Siberian Branch of the Russian Academy of Sciences, SPIE Russian Chapter, International Science and Technology Center, Tomsk Innovation Center of Laser Technologies, Laser Association, Surgut State University, and TOPAZ Research and Innovation Enterprise.
The conference involved more than 160 participants from Russia, USA, Germany, France, Bulgaria, Yugoslavia, Iran, Kazakhstan, Netherlands, South Korea, and Switzerland, who presented more than 60 oral and 140 poster reports. In addition, about 50 students of Tomsk universities took part in the conference.
During the conference, the participants had a possibility to visit research laboratories of the Institute of High-Current Electronics SB RAS, the Institute of Atmospheric Optics SB RAS, Tomsk State University, and Siberian Physical-Technical Institute.
This year, the conference was supported, for the first time, by the International Science and Technology Center. The support allowed the conference to involve additional participants from the Russian Federation and to improve its organization due to the modern presentation equipment, synchronous translation, a possibility of meeting the participants in the Tolmachevo International Airport (Novosibirsk), etc.
In 2004, some reports will be published in Proceedings of SPIE ( 2004, Vol. 5483), and the reports presented at the conference in Russian are published in this issue of Atmospheric and Oceanic Optics (2004. Vol. 17. No. 2-3).

Let us review briefly the reports presented at the conference.
The Plenary Session on 15th of September incorporated papers devoted to the urgent problems of development of pulsed lasers and spontaneous emission sources, as well as their applications. The session was opened with the lecture by A.N. Soldatov (Tomsk State University) devoted to the history of starting the first laser in Tomsk and the review of investigations of Tomsk scientists in quantum electronics.
The report on the processes of discharge formation and generation of electron beams in dense gases (S.I. Yakovlenko, General Physics Institute RAS, Moscow) has attracted considerable attention. A.A. Sinyanskii (VNIIEF, Russian Federal Nuclear Center, Sarov) told about multichannel nuclear-pumped quasi-continuous laser setups developed in VNIIEF. U. Kogelschatz (ABB Corporate Research, Switzerland) presented an interesting paper "Excimer lamps: History, discharge physics, and industrial applications". The report "Non-self-sustained electric discharge in oxygen gas mixtures: singlet delta oxygen production for an oxygen-iodine laser" was presented by A.A. Kotkov (P.N. Lebedev Physical Institute RAS, Moscow). A.M. Razhev (Institute of Laser Physics SB RAS, Novosibirsk, Russia) reviewed the researches and the progress achieved in the development of discharge-pumped exciplex lasers and their application in ophthalmology. J. Wieser (Germany) presented the paper "Electron beam pumped ultraviolet light sources". V.F. Tarasenko reviewed the results obtained in the Laboratory of Optical Radiations of the Institute of High-Current Electronics SB RAS (Tomsk) for two years between the AMPL-01 and AMPL-03 conferences.

Session A. Gas and Plasma Lasers

That session incorporated 31 papers, including 9 oral ones. The distribution of the scientific interests to different types of lasers can be illustrated by the following statistics. Various aspects of excimer lasers were considered in 13 papers. Four papers dealt with laser effects in the atomic Õå, four papers were devoted to molecular ÑÎ2 lasers, and 4 works considered chemical lasers. Two papers challenged the nitrogen lasers; plasma lasers were discussed in one paper, as well as an ionized argon laser, and two papers dealt with other media. To be noted is the considerable interest to the xenon laser, in particular, with nuclear pumping, and to non-chain chemical lasers.
So, it can be concluded that the investigations in the field of gas lasers have been intensely developed, and gas lasers are still beyond comparison in generation of short UV and VUV radiation.

Session B. Metal Vapor Lasers

The conference traditionally paid a considerable attention (about 30 works) to metal vapor lasers (MVLs) and their applications. Most papers, as usually, dealt with copper vapor lasers, but the number of papers addressing physics and chemistry of additives in the active medium, problems of salt injection of vapor, stabilization of the medium physical and chemical composition, and physics of longitudinal energy-tense repetitively pulsed discharge has increased significantly.
G.G. Petrash and K.I. Zemskov (P.N. Lebedev Physical Institute, Moscow) considered a possibility of the pulsed inversion in the processes of the ion-ion recombination, H. Latifi (Laser Research Institute, Teheran, Iran) reported the results of research into the effect of the longitudinal magnetic field on the characteristics of a ÑuBr laser, M.A. Kazaryan with colleagues (RPE "Istok," Fryazino, P.N. Lebedev Physical Institute, Moscow) reported the development of commercial sealed-off copper vapor lasers with the mean output power higher than 100 W from one active element at a possible service life no less than 2000 hours. Further enhancement of the output characteristics requires solving the thyratron problem and developing new circuit designs. V.M. Klimkin (Institute of Atmospheric Optics SB RAS, Tomsk) has exemplified the repeated contraction of the discharge in metal vapor lasers. Injection of vapor into the discharge by placing a metal directly on the surface of the discharge channel is not optimal - the metal should be placed so that the vapor density in the channel is lower than the equilibrium level. O.O. Prusakov with co-authors (Rostov State University) presented a self-consistent mathematical model of a recombination laser and predicted a possibility of lasing at new lines of the strontium ion. N.A. Yudin (Institute of Semiconductor Physics SB RAS, Novosibirsk) informed the auditory about his study of the effect of the prepulse electron concentration on the efficiency of a copper vapor laser. V.V. Tatur with co-authors (Institute for Optical Monitoring SB RAS, Tomsk) has studied the ÑuBr laser in the circuit with bipolar transistor power supply. V.M. Klimkin and V.G. Sokovikov (Institute of Atmospheric Optics SB RAS, Tomsk) have addressed the pulsed laser IR transitions in the spectra of strontium, thulium, and ytterbium, which cannot be attributed to the r-m schemes. They have put forward the hypothesis that these transitions are excited by the resonant pulsed radiation of atoms through the molecular component of vapor. G.S. Evtushenko with colleagues (Institute of Atmospheric Optics SB RAS, Tomsk) presented the results of investigation of the r-m transitions in lead at discharge excitation in PbBr2 vapor and the effect of Í2 additives into the CuBr-Ne laser mixture. V.A. Gerasimov with co-authors (Institute of Atmospheric Optics SB RAS, Tomsk) has investigated the laser transitions in thulium, erbium, and mixtures of rare-earth elements, which can and cannot be attributed to the r-m schemes. The paper by T.M. Gorbunova with co-authors (Tomsk State University) discussed the results of investigation of laser transitions in the triplet system of strontium atomic terms. A.N. Soldatov with colleagues (Tomsk State University) reported the development of the strontium vapor laser with the total output power higher than 5 W in the IR spectral region. V.A. Gerasimov with colleagues (Institute of Atmospheric Optics SB RAS, Tomsk) informed the auditory about the effect of the recovery of the service life of the metal laser gas discharge tubes upon exterior heating. V.G. Sokovikov with colleagues (Institute of Atmospheric Optics SB RAS, Tomsk) reported the observed lasing effects at triplet transitions of the mercury atom upon propagation of the radiation with the doubled and overall frequencies of the Cu laser through a cell filled with the mercury vapor.

Session C. Dye Lasers and Photoprocesses in Complex Organic Molecules

The interest to the photoprocesses proceeding in complex organic molecules is caused by new applications of solid-state materials based on these molecules in opto-electronic systems and devices (light emitting diodes, emitters of optical radiation, microlasers, various devices in telecommunication systems). Urgent problems are the development and creation of diverse thermally stable organic molecules efficiently emitting in the solid state under optical and electrical excitation. Complex molecular systems with the transfer of electronic excitation energy, luminescent polymers, and solid solutions of organic molecules in various matrices can be considered as such molecules.
R.T. Kuznetsova (Siberian Physical-Technical Institute, Tomsk) in her report considered photostability features of laser dyes at the pump power density up to 300 MW/cm2. It was shown that the laser photostability and the quantum yield of laser dye phototransformations depend on the intensity and polarization of the pump radiation.
The two-photon induced luminescence in organic dye drops in high-power light fields was considered in the report by A.A. Zemlyanov (Institute of Atmospheric Optics SB RAS, Tomsk) and V.A. Donchenko with co-authors (Siberian Physical-Technical Institute, Tomsk). A considerable interest was attracted to the report by A.V. Kukhto with co-authors (Institute of Atomic and Molecular Physics, Minsk, Belarus; Chuvash State University, Cheboksary, Russia) devoted to energy conversion in the laser dye vapor under the electron beam excitation. The studies of such kind are needed for search for organic molecules fluorescing under excitation by the electrical current.
The properties of organic molecules in thin films were treated in the report by A.O. Bulanov with co-authors (Institute of Physical and Organic Chemistry, Rostov). They presented the results of investigation into the photochromic properties of idolinospiran in polymer matrices and polydisperse films. The photochromic properties manifesting themselves in the solid phase are characterized by a high value of free energy of activation of the thermal ring-opening reaction.
Complex molecular systems like bifluorophores are promising for new applications, therefore the reports devoted to the subject by G.V. Mayer, V.Ya. Artyukhov (Siberian Physical-Technical Institute, Tomsk State University) and V.I. Yuzha-kov with co-authors (Moscow State University) have attracted a considerable interest.
Some reports presented the results of investigation of photoprocesses in organic molecules by quantum chemical methods (V.Ya. Artyukhov, N.Yu. Vasil'eva, O.K. Bazyl', and others (Siberian Physical-Technical Institute, Tomsk)).
In the report by I.V. Sokolova, O.N. Tchaikovskaya, V.A. Svetlichnyi, N.B. Sultimova, and others, photoprocesses in organic environmental toxicants were studied and a method has been proposed for their optical diagnostics and decomposition.
To be noted is the active participation of young scientists (E.I. Sinchenko, V.A. Svetlichnyi, N.B. Sultimova, N.E. Kovalskaya, O.V. Dolgova, V.A. Pomogaev, A.V. Firyulina, S.V. Nikolaev, O.V. Vusovich, E.A. Vostrikova, P.P. Mizin, N.S. Savenkova, A.V. Vasil'ev), who, hopefully, will contribute appreciably to solution of scientific problems for further development of laser technologies.

Maltsev with co-authors (Institute of Atmospheric Optics SB RAS, Tomsk) presented the results of investigation into generation of high-current subrelativistic electron beams in gases. The subrelativistic electron beams were obtained experimentally in gas discharges of different types: the corona discharge, the discharge sliding on a surface, and their combination. V.F. Tarasenko and V.M. Orlovskii (Institute of High-Current Electronics SB RAS, Tomsk) presented the experimental results on generation of the electron beam in gases at the atmospheric pressure and e-beam output through a foil into the space behind the anode.
