“…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.
