摘　　要：全固态单频单模激光器的频率稳定性以及最佳匹配输出功率对温度非常敏感。本文介绍以AT89S52单片机为核心的激光器恒温控制系统的硬件与软件的设计与实现,以及热敏电阻的线性插值化处理,温度设定精度最小可达0.01℃。实验结果表明:该激光器恒温控制系统的温度控制稳定度可达5m℃,并且温度设定非常灵活。Frequency stability and the best match output power of the full solid-state single frequency single mode laser are extremely sensitive to the temperature. This article introduced hardware and the software design and realization of laser constant temperature control system centered by Microcomputer AT89S52, as well as thermistor linear interpolation processing, minimum of temperature setting accuracy can reach 0. 01℃. The experimental result indicates： temperature controlling stability of laser constant temperature controlling system may achieve 5 m℃, and temperature setting is extremely flexible.
