In this article, a hollow cathode He-Kr+ laser was operated at 469.4 nm and was excited by a 50 Hz near-square wave, maximum 10 A, 500 mu s duration current pulses.Abstract:
Operation characteristics of a short, 10 cm active length hollow cathode He-Kr+ laser were investigated. The laser operated at 469.4 nm and was excited by a 50 Hz near-square wave, maximum 10 A, 500 mu s duration current pulses. The lowest threshold current observed was 0.9 A and a maximum laser power of 2.7 mW was obtained. Laser oscillation was also observed at high He pressures, at 104 mbar the output power was 1.5 mW. The shape of the laser pulse showed a characteristic change with increasing He pressure. Saturation of laser power with increasing discharge current was observed even at high He pressures. The saturation is considered to be caused by the appearance of sputtered Al vapour.read more
