Average power limitations in high-repetition-rate pulsed gas lasers at 10.6 and 16 microm.

Processes resulting in average power limitations in high-repetition-rate pulsed lasers are studied. The description and performance of a CO(2) laser with an average power up to 10 kW as well as of an optically pumped CF(4) laser are given.

TIR-1 carbon dioxide laser system for fusion.

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.
