A final DF-CО2 amplifier of the multi-terawatt picosecond 10 micrometer laser system

Experimental technique and devices

The paper presents the results of measurements of the gain and the energy of the amplified spontaneous luminescence of pulsed chemical DF-CO2 amplifier at an active medium pressure up to 2.5 atm. The values obtained and the large amplifier aperture (100 mm) allow to use it as a final amplifier of the multiterawatt 10-µm picosecond laser system.
