A theoretical and experimenal investigation was made of the possibility of generating light pulses of energy of the order of 1J and nanosecond duration in a freely oscillating CO/sub 2/ laser. The pulses obtained were of approx.10 nsec duration when the laser efficiency was approx.8%. It was found that the pulse duration depended on the composition of the gas mixture (the CO/sub 2/:N/sub 2/:He=1:0.5:3 mixture was found to be optimal), resonator length, transparency of the exit mirror, and excess of the total gain of the active medium above the losses.
