Synchronization effect on the small-signal gain and saturation intensity of a CuBr laser

A pair of copper bromide laser in an oscillator–amplifier configuration was used to investigate the small signal gain and saturation intensity as amplifying parameters, versus delay time of triggering between lasers. The maximum amplifying parameters and output power of 0.07 cm^?1, 43 μJ cm^?2, and 9 W were measured, respectively at optimum delay time of about 10 ns. The amplifying parameters and measured output power of laser versus delay times between intervals of 6–43 ns, shows some local maxima and minima. The output power extracted from the amplifier exceeds that achieved with the same device as the oscillator by more than 60%.
