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
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
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.

generation: the electron emission mechanism, electron runaway conditions, measurement technologies, setup
design, etc. S.I. Yakovlenko and A.N. Tkachev (General Physics Institute RAS, Moscow) have analyzed the
mechanism of electron runaway and the role of the effect in the gas breakdown. Three reports by A.N. 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. G.V. Kolbychev

rather wide and included the issues of laser separation of isotopes, as well as modernization and creation
of new laser systems for medicine and industry. Several reports were devoted to new effects in the laser
radiation interaction with matter.
The plenary session was opened by A.N. Soldatov, who, on behalf of the Tomsk State University, Vanderbilt
University (USA), and the Pulslight Company (Bulgaria), has set out the report "A sealed-off strontium-vapor
laser." He told about investigations into the SrI and SrII vapor laser, which resulted in creation of the

to the study of new properties of the optical pulsating discharge (OPD) in gas, generated by periodic laser
radiation at the pulse repetition frequency of ten kilohertz in comparison with a single laser spark or
continuous optical discharge. The OPD properties discussed in the report significantly extend the
applications of high-power lasers. The conversion mechanism of laser radiation into quasistationary waves
is also of interest for acoustics and explosion physics as a new approach to generation of low-frequency
waves using point low-energy sources.
V.M. Klimkin (Institute of Atmospheric Optics SB RAS, Tomsk) has considered the promises of binary gas
mixtures (like He-Ne mixture) for excitation by longitudinal repetitively pulsed discharges using the
