In order to simultaneouly generate the laser output with nearly equal power for dual wavelengths of 1319nm/1338nm in the LDA side pumped Nd:YAG laser,two methods that uses a Brewster′s window and optimizes the transmissions at 1319nm and 1338nm of output mirror and reflection mirror at the same time are adopted.In this experiment,a CW LDA pump module made in China has a side pumping structure,and the highest power of LDA is 600 W.The maximum power of CW dual wavelength output is 30 W,and when th...
