Stabilization of the output power of an LGI-101 copper vapor laser

A study was made of the influence of the pulse repetition frequency on the output and pump parameters of an LGI-101 copper vapor laser. It was found that the pump and output powers could be stabilized by variation of the pulse repetition frequency. A stabilization unit capable of maintaining the output power constant to within ± 5%, for changes in the line voltage of ± 20 V, was constructed. In the absence of this unit similar changes in the line voltage quenched the lasing action.
