Abstract

An efficient nitrogen laser has been developed. The exciter of the nitrogen laser employs a magnetic pulse compression circuit. A laser pulsed energy of 20 mJ is achieved under a single-pulsed mode, with an efficiency of 1.3% to the output energy of the exciter, and 0.43% to the charging energy. Several types of electrodes were tested. A maximum efficiency and laser light pulse energy are obtained with triangular-rectangular electrodes and at a laser gas pressure of about 100 Torr
