【Abstract】 In the hi power DPL system, the heat charge of the laser diode affects the quality of laser beams seriously. We have done some experiments to study the phenomena, and developed measures to dissipate the heat of the laser diode. The measures include inner ice water circulation technology, TEC cooling technology and temperature controlling technology. Adopting these measures in a 15 W CW LD pumped Q switched Nd:YAG laser, we obtained a steady 1 06 μm laser output with a 10 kHz repetition rate, a 25 kW peak power, and a 10 ns pulse width.更多还原
