Abstract
Use of a gas-filled spark gap in the pump system of a UV N-2 laser all owed the lasing efficiency to be increased up to (4-5) x 10(-4) and en sured obtaining of an average power above 30 mW (a short-time peak pow er up to 0.3 W) and a pulsed power above 50 kW with an air-cooled syst em. The angular power density in the diffraction limited beam exceeds 10(11) W/sr. Stable operation of the spark gap was observed for a puls ed power supply with the pulse repetition frequency up to 1 kHz and a switched energy of up to 1 J.
