Abstract

During recent years pulsed CO_2 lasers for fusion research have been under construction in the I. V. Kurchatov Institute of Atomic Energy and the D. V. Efremov Electro-Physical Apparatus Institute. Efforts are being concentrated at present on two approaches: (1) microsecond laser pulse plasma heating in solenoids and θ pinches (UTRO system) and (2) nanosecond CO_2 laser utilization for inertial confinement fusion. The TIR-1 system was created to develop nanosecond CO_2 laser technology and to study laser–target interaction at 10 μm. This system is designed to deliver ~1-kJ energy in one beam of ~1-nsec duration. The TIR-1 system consists of an oscillator–preamplifier system that produces an ~1-nsec laser pulse with an energy contrast ratio of ~10^6, a large-aperture (30 × 30-cm^2) triple-pass amplifier capable of providing ≈1 kJ in a 1-nsec pulse, a target chamber with diagnostic equipment, and associated engineering systems.

Author

Anisimov, V. N., Arutyunyan, R. V., Baranov, V. Yu., Bolshov, L. A., Velikhov, E. P., Dolgov, V. A., Ilyin, A. I., Kovalevich, A. M., Kraposhin, V. S., Malyuta, D. D., Matveeva, L. A., Mezhevov, V. S., Pismennyi, V. D., Sebrant, A. Yu., Stepanov, Yu. Yu., and Stepanova, M. A.

Abstract

Recently created pulsed gas lasers with high pulse repetition rate produce radiation in the IR [ V. Yu. Baranov , in Molecular Gas Lasers. Physics Applications, VelikhovE. P., Ed. ( Mir, Moscow, 1981), pp. 252– 255] and the UV ( V. Yu. Baranov , in Proceedings, International Conference on Lasers, 14–18 Dec. 1981, pp. 968– 974) regions of the spectrum. These lasers are widely used in research on the selective excitation of matter. This field of study includes laser isotope separation { G. I. Abdushelashvili , Kvantovaya Elektron. (Moscow)9, 743 ( 1982) [ Sov. J. Quantum Electron.12, 459 ( 1982)]} and laser-induced chemical reactions [ V. Yu. Baranov , Preprint IAE 3693/13 ( Moscow, 1982)]. But there are few publications dealing with uses of high-repetition-rate lasers for materials processing, although this problem undoubtedly is of considerable scientific interest.
