Abstract

When the laser terminal guidance system is working, the irradiator emits re-frequency laser pulses that precisely control the light time, so as to provide the seeker with an accurately identified signal source, while avoiding enemy laser interference. The laser irradiator uses electro-optic Q-switched technology to obtain pulses with high pulse energy and precise time control. An experimental device for testing the output pulse time of the electro-optic Q-switched laser was designed. The experimental analysis the action process of the electro-optic effect of the KD*P crystal. The effect of the delay time of Q-switched on the output energy and pulse width of the laser was tested and discussed. The results show that the setting of the optimal delay time can increase the output energy of the laser, which has a positive significance for controlling the light time of the irradiator of laser terminal guidance system.
