摘　　要：更快的调Q开关速度以进一步提高峰值功率并压缩脉宽将会使电光调Q技术在激光打孔、划片、雕刻和测距等领域得到更广泛的的应用。设计了一种新型的高速电光调Q开关驱动电源,包括高压电源、高速开关电路、触发电路和控制电路等,该驱动电源具有体积小、功耗低和工作寿命长等优点。经实验,下降沿在20ns以下,高压在2KV至5KV可调,重复频率可达10KHz。Faster Q-switch speed can further improve high peak power and Compressing pulse width, so the technology of repetition electro-optic Q-switch has been developed rapidly in laser boring.scribing.carving and ranging etc. A novel quick electrooptic Q-switch power supply is designed in this paper, including high-voltage power.quick switching circuit.trigger circuit and control circuit etc. The power supply has many merits such as small bulk.low power dissipation and long operating life etc. The experiment demonstrates that the falling edge below 20ns, adjustable high-voltage power between 2KV to 5KM, high repetition rate of 10KHz.
