Embodiment Construction
[0028] Such as figure 1 As shown, the present invention consists of a full anti-cavity plate 1, a Q-switching crystal 2, a polarizer 3, a xenon lamp 4, a laser rod 5, a light-gathering cavity 6, a wave plate 7, an output cavity plate 8, and a voltage-reducing Q-switching circuit board 9 , Laser power supply 10 and laser water cooling system 11 constitute.
[0029] The xenon lamp 4 is placed in parallel under the laser rod 5, and the laser rod and the xenon lamp are installed in the light-concentrating cavity 6 at the same time. Pumping; the laser water cooling system 11 is connected to the inside of the light collecting cavity 6 to provide constant temperature cooling for the laser rod; the wave plate 7 uses a 1 / 4 wave plate to compensate for the thermal depolarization problem under high pump power; The polarizer 3 adopts 2 to 5 pieces of white gemstones (Al 2 o 3 ) and other materials are used to generate linearly polarized light; the Q-switching crystal 2 and the polarize...
