Experimental study of cavity length influence on lasing characteristics Q-Switched Nd:YLF laser

Abstract

Abstract The influence of the resonator configuration on the temporal characteristics of Nd: YLF crystals laser generation in the region of frequency degeneracy of the transverse modes of a resonator operating in the Q-Switch mode is studied. It is shown that in the degeneracy regions, the pulse duration stretches, while the peak pulse amplitude and the pulse repetition period decrease.
