High efficiency LD side-pumped green laser

    Graphical Abstract
    • Abstract
  • According to ABCD transmission matrix theory, A Z-type resonator used for laser diode (LD) side-pumped intracavity frequency-doubled Nd:YAG /KTP laser was analyzed and calculated by software Matlab. We selected a set of proper cavity parameters, at 9kHz repetition frequency and 302.5W input electrical power, a 17.27W green laser was obtained with an electrical-optical conversion efficiency of 5.7% and divergence angle of 0.68mrad, the beam quality was M2x=3.351, M2y=3.759，output instability was less than 0.9%.
