Lasers developed in the Institute of Atmospheric Optics of the SB RAS (a review)

The results of research on the development of the first electric discharge lasers on active media N2, CO2, Cu, CuBr and excimer molecules at the Institute of Atmospheric Optics named after V. E. Zueva SB RAS are given. It created one of the world's first Cu-lasers with a pulse production of copper vapors due to the explosion of conductors and a transverse excitation discharge. For a copper laser, record specific generation parameters were obtained almost equal to the limit: radiation energy 2.4 J/l, peak power 120 MW/l with an efficiency of 0.16 %. For the CuBr laser operating in frequency mode, for the first time, an average radiation power of more than 100 W was obtained. In the dual pulse excitation mode, conditions were found that limit the growth of the efficiency of the CuBr laser. For him, a record efficiency of 2.7 % was obtained. For the first time, a nitrogen laser was developed with a maximum efficiency of 0.27 % with an energy of 0.8 mJ, a peak power of 160 kW. For the first time, a miniature XeCl laser with a longitudinal excitation discharge was developed, which worked both with and without buffer gases He, Ne and Ar.

Studying the Variations in Aerosol Loading and Thermal Regime of the Stratosphere Over Tomsk on the Basis of Lidar Monitoring

One of the important applications of lidar techniques is the study of aerosol content and thermal regime of the stratosphere. Such investigations in monitoring mode were initiated at the Institute of Atmospheric Optics since 1986 (for aerosol) and 1994 (for temperature), and are continued to the present. The main attention is paid to studying the annual variations in aerosol content in the stratosphere and sudden disturbances caused by winter stratospheric warming. In this paper we present the results of studying the aerosol content and its vertical stratification and vertical distribution of temperature in the stratosphere over Tomsk for the last three years.

THE STUDY OF THE DYNAMICS OF THE THERMAL REGIME OF THE STRATOSPHERE OVER TOMSK

Одним из важных применений лидарных технологий является исследование термического режима атмосферы. Такие исследования в мониторинговом режиме в институте оптики атмосферы СО РАН были начаты с 1994 года и продолжаются в настоящее время. Особое внимание уделяется изучению проявления внезапных возмущений в средней стратосфере, вызываемых зимними стратосферными потеплениями (СП). С полученными по данной тематике результатами можно ознакомиться в работах 1- 8. В настоящей статье представлены исследования вертикального распределения температуры над Томском в возмущенный и спокойный периоды 2018 г. One of the important applications for lidar technologies is to study the thermal regime of the atmosphere. In V.E. Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, these studies in a monitoring mode have been initiated since 1994 and continue into the present. A special attention is devoted to studying the manifestations of sudden disturbances occurring in the middle stratosphere under the influence of wintertime stratospheric warmings. In this paper we present the studies of the vertical temperature distribution over Tomsk in disturbed and quiescent periods of 2018.
