Jinan nanosecond toelectric technology co., LTD., growing DKDP crystal independently. The optimized electro-optic Q switch made of DKDP crystal is suitable for electro-optic Q-modulated laser with wave length of 250nm-1300nm. By applying pulse voltage to Q switch, the of inversion of upper level particles in laser material and Q factor of laser resonator can be controlled, so that the laser beam produced a peak power of several hundred megawatts to gigawatt level.
