On Optimality of Stable Amplitude of Laser Pulse by Electro-Optical Deflector

The article explains working principle producing laser pulse with stable amplitude by high voltage electro-pulse generator to drive LiNbO3 electro-optical reflector quickly reflecting laser pulse;and analyses experimental results of amplitude stability of laser pulse by electro-pulse generator made from cold-cathode tube, avalanche transistor and MOS transistor respectively. Comparing the effect on stable amplitude by three types of electro-pulse generator,the results show that if replace imported cold-cathode tube with either avalanche transistor or MOS transistor, a fine stable amplitude of laser pulse is obtained also. There are certain actual significance in the domesticalization of electro-optical devices.
