The paper presents the experimental results of developing a power supply for metal vapor lasers excitation which include three separate pump sources. Source control is carried out using a PC with developed software, which provides flexible configuration of excitation parameters. The use of three sources allows increasing the excitation power while maintaining comfortable operation conditions for the switch. Waveforms of the sources operation in the separate and simultaneous operating modes are presented. The main parameters of the discharge are estimated.
We present the amplifying features of the copper bromide brightness amplifier excited by a capacitively coupled longitudinal discharge. The dependences of the amplified spontaneous emission (ASE) power, gain, and the sensitivity of the brightness amplifier on the pulse repetition frequency (PRF) of the excitation have been obtained. The PRF of excitation varied from 12 to 24 kHz. At PRF 24 kHz, the output power was 2.1 W, pulse duration was 30 ns that is lower than for a copper bromide brightness amplifier with the typical excitation pulses. The small-signal gain reaches 0.25 cm − 1, which is commensurate for a copper atom active media with the typical excitation charge. The sensitivity of the investigated amplifier is 0.01% of ASE power in the studied PRF range.
