Abstract: A scheme of the experiment is described and the results of measuring the small-signal gain in the active medium of a pulsed chemical DF — CO₂ laser at a medium pressure in the range from 1 to 2.5 atm are reported. The values obtained (above 5 m^-1 at a pressure of 2.5 atm) make this laser a promising final amplifier of a multiterawatt laser system in the 10-μm wavelength region.

Keywords: DF — CO₂ laser, small-signal gain.
