| 摘 要： | 针对自制的852nm外腔半导体激光器，设计了一套低漂移的外腔半导体激光器驱动电路。通过恒温控制模块控制激光二极管的温度，高稳恒流源驱动激光二极管，外腔温控电路用于外腔的温度控制，高压恒压源控制外腔中压电陶瓷的长度。阐述了各部分电路的工作原理，并为降低激光器的频率漂移对电路做了优化。测试结果显示，1h内激光器频率漂移降为15MHz。

| Abstract: | To drive a home-made 852 nm external cavity semiconductor diode laser(ECDL), an electronic system of ECDL with low frequency drift is designed. The laser diode is regulated by a temperature controller and a stabilized constant current source. And the external cavity length is regulated by another temperature controller and a constant voltage source with high voltage. By designing the driving circuits and choosing the components, the frequency drift of the ECDL is reduced to 15 MHz/h according to the test results. |
