Paper Abstract

We analyzed graphically the resonator stability versus the thermal focal length and the thermally induced birefringence, as well as the fundamental spot size on the laser rod for a green laser of Nd:Y3Al5O12 (Na:YAG) on high-gray-tracking-resistivity KTiOPO4 as a function of the pumping power for r- and θ-polarization beams. The spot size distribution of the second harmonic and the fundamental wave in the folded cavity are also presented. On the basis of the theoretical analysis, an average power of 185.21 W was obtained with an intracavity frequency-doubling two-diode-side-pumped Nd:YAG laser system with twin acoustic-optical modulators, and the pulse width was 180 ns at a repetition rate of 10 kHz when the pumping power of each laser diode module was 600 W. The optical-to-optical conversion efficiency was 15.4%, and the beam quality factors were Mx2 =9.52, My2=9.86.
