Carbon dioxide laser with an output energy of 3 kJ, excited in matched regime

An investigation was made of a CO₂ laser with pulsed pumping of a gas cell in the matched regime. The total energy of the output radiation was 3 kJ when the pressure of the mixture was 2 atm and the active volume was 50 liters. When the active volume was 12 liters, the energy deposited in a mixture of the CO₂:N₂:He = 1:2:2 composition was 0.6 kJ·liter^–1·atm^–1 and the radiation energy was ~80 J·liter^–1·atm^–1.
