The model of transparent conductive film electro-optic switch was established. The optimal switch design parameters were used to analyze the time characteristics and thermal effect of the switch. The simulation results show that the switch rising time reaches the nominal time requirement. Under the high average power load, the influence of the temperature rise of the crystal on the switching performance is small. The thin-film electrode electro-optic switch of this configuration can be applied to high-power laser systems operating under repetitive frequency.
