摘要
以光栅外腔半导体激光器(ECDL)作为光源，获得了铯原子D2线B线(6 2S 1/2 F=4→6 2P 3/2 F′=3,4,5)У牡髦谱移光谱(MTS)。与传统的饱和吸收光谱作了比较，并对不同调制频率下的调制转移光谱特性作了实验研究。将频率调制信号直接加在声光频移器上，相对简化了调制转移光谱的实验装置。
Abstract
Employing a grating-external-cavity diode laser (ECDL) as laser source, the modulation transfer spectrum (MTS) of cesium D 2 line (6 2S 1/2 F=4→6 2P 3/2 F′=3,4,5) is obtained. Instead of using a electro-optical modulator (EOM), a directly frequency modulation to an acousto-optical modulator (AOM) in MTS device is adopted, which more or less simplifies the spectroscopic device. Under different modulation frequencies the character of MTS is investigated experimentally.
