0．9～0．95μm波段钛宝石激光器波长自动调谐实验

The Autoscan Experiment of Ti:Sapphire Laser in 0.9～0.95 μm Wavelength Range

利用自制的激光波长计和相应的接口电路，在ＣＲ８９９－２１激光器上实现了钛宝石激光器０．９～０．９５μｍ波段的波长自动扫描控制。实验结果表明，连续扫描宽度可达２００ＧＨｚ，波长连接精度好于＋２００ＭＨｚ。这为０．９μｍ以上的分子高分辨光谱研究提供了必要的实验手段。

A CW Ti:sapphire laser was automatically tuned to 200 GHz in 0.9￣0.95 μm rangewith a wavemeter and relevant interface circuit developed by ourselves while retaininga narrow spectral width of 500 kHz(rms). The scan nonlinearity was corrected with anaccuracy of ±500 MHz and the single scans joined together with an accuracy of ±200MHz. The experimental system has proved useful for the molecular spectroscopy study.
