“…The effect arises in the laser tube, which performs both as an optical and an acoustic resonator depending on the PRF [7]. The reproducible fluctuations in the output power of CuBr and gas lasers at different PRFs have been observed previously [5,[9][10][11][12]. Furthermore, the master oscillator-power amplifier (MOPA) array has been used extensively in order to determine the small-signal gain (g 0 ) and saturation intensity (E S ) as laser amplifying parameters, and to satisfy higher output power and beam quality simultaneously [13][14][15][16].…”

Oscillations in the output power of halide lasers were recorded by varying the excitation frequency from 11.7 to 30 kHz. An effect arises in the laser tube, which performs both as an optical and an acoustic resonator at the acoustic resonant frequencies, just like other metal vapor lasers. It is shown that a similar effect occurs when amplifying the parameters of lasers. In other words, the oscillatory behavior of laser output power comes from the competition between the microscopic laser parameters and the excitation frequency as an operational and macroscopic parameter.

“…As it has already been mentioned in a number of previous works, the visualization of fast processes blocked by the broadband background radiation is possible with the use of systems with brightness amplifiers based on metal vapors [3][4] and their halides [5,6]. The use of such systemslaser monitors -allows to perform high speed imaging of processes, while the time resolution is limited by a recorder (camera) and the brightness amplifier PRF.…”

The imaging results of different processes blocked from the observation by the intense background light are presented in this paper. Active optical systems based on high-frequency brightness amplifier are used to decrease the negative factor of the glare. The experimental and modeling results on obtaining high pulse repetition frequencies (PRF) (more than 100 kHz) of copper bromide vapor brightness amplifiers operating in a low input energy mode are shown. The use of metal vapor brightness amplifiers for visual non-destructive testing of fast processes obscured by the glare is also discussed. It has been shown that the imaging method proposed in this paper proves to be the most reliable to obtain the information about objects or processes in a real time mode using high PRF CuBr active media.
