Abstract:

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.
