摘　　要：工程应用需求声光Q开关的工作温度范围较宽,声光Q开关的器件受温度变化影响很小,可忽略,但驱动器受温度变化的影响较大,传统驱动器低温输出功率特性极不稳定。该文介绍了一种晶体管与场效应管相结合的方法,取得了良好的效果,解决了功率不稳定性问题。The engineering applications demands wide range of working temperature for acousto-optic Q switch. The temperature change has little effect on acousto-optic Q switch and can be negligible, but is has great effect on the driver and the low temperature power output characteristic of conventional driver is extremely unstable. A meth- od combining the transistor and the MOSFET is introduced in this paper. The problem of power instability has been solved by using this method and good result has been obtained.
