Laser monitor for imaging of the processes located at different distances

Actual methods of the long lasing pulse obtaining in CuBr active medium was observed. A compact pump source, which can be used in mode with low energy input in the discherge was developed. The source is stable working in low frequencies (2-3 kHz) and allows to achieve a pulse duration up to 100 ns. Moreover, this source allows to operate with the pulse repetition frequency of up to 50 kHz. Developed device was used to study the influence of the distance between the observed object and the brightness amplifier on the image quality and on the process of signal amplification in active medium. In case of working in the mode with atypical duration of laser pulse it is became possible to image the objects at a distance up to 9 meters with no loss in images quality.
