Abstract  We report a wavelength-locked 914 nm  laser diode  in-band pumped intra cavity efficient green laser, in our experiment, a wave-locked 914 nm laser diode was used as a pumping source, which improve pump uniformity and pump efficiency and reducing the thermal effect of the laser greatly, thus, a high beam quality 532 nm laser output is obtained. When the pump power is 18 W and the repitition rate is 130 kHz, a green laser output of 6.7 W is obtained, and the conversion efficiency is 37.2% for pumping power of 18 W, which corresponds to a conversion efficiency of 60% for absorbed pumping.

Severe thermal effects can lead to deterioration of the beam quality of the laser, thermal s...

This is a  Q-switched laser , the wavelength is 1064nm. It’s a very popular Lab pulsed laser system. This laser does not have a CW continuous operation mode.  The power supply to  CW  is a mode for manually adjusting the frequency. Adjusting the current is to adjust the frequency, that is, to adjust the average power.
