| 摘 要： | 利用铯原子D2线的调制转移光谱的鉴频特性,实现了光栅外腔式主振荡器-功率放大型(MOPA)半导体激光器相对于铯原子62S1/2F=4→62P3/2 F’=5超精细跃迁的偏频锁定,在100 ms内激光频率的相对起伏小于±280 kHz.相对于一般的饱和吸收锁频方法而言,调制转移光谱在锁频中的应用不仅彻底消除了Doppler背景对锁频的影响,而且还避免了对激光器直接进行频率扰动而带来的附加频率噪音.

| Abstract: | Employing the frequency discriminating character of the modulation transfer spectrum(MTS) of cesium D2 line a grating-external-cavity master-oscillator-power-amplifier(MOPA)-type semiconductor laser is stabilized to cesium 62S1/2F=4→62P3/2F’=5 hyperfine transition. A frequency jitter of less than ±280 kHz in 100 ms is estimated based on the error signal in the preliminary stabilization. The application of MTS in laser frequency stabilization can not only completely remove the Doppler background and its negative influence, but also avoid extra frequency noise due to the frequency dither to laser in the normally used saturation absorption locking technique. |
