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.
The control system for bistatic laser monitor was developed. This system includes digital circuit and high-voltage modulator. The control system provides synchronous pumping of two active elements: an illumination source and a brightness amplifier. The time shift between triggering pulses is regulated by a variometer and its maximum value is 40 ns in case active load. The MOPA system was realized. Experiments on visualization of a test object were done. The example of such visualization was demonstrated.
