Research of 1.32-um Nd:YAG laser and its second harmonic generation (SHG) 0.66-um laser

摘要

Abstract: Under the normal temperature, Nd:YAG crystal has three fluorescence spectrums, the strength of 1.06 $mu@m spectrum is nearly 4 times to that of 1.32 $mu@m's, only by selecting frequency method, 1.32 $mu@m oscillation can be obtained. Modulating the 1.32 $mu@m wavelength and doubling its frequency, 0.66 $mu@m the SHG of 1.32 $mu@m can be output. In this experiment, we obtain 23.7 W 1.32 $mu@m maximum laser output and 500 mW 0.66 $mu@m red laser output.!5
