摘要

我们研究了196.0 THz (1529 nm) DFB激光器在384 THz (780 nm)光泵浦铷蒸气吸收谱线上锁频的性能。我们描述了一个简单的理论模型，给出了这种蒸汽的吸收剖面。两个DFB激光器频率锁定到这些线的测量频率稳定性达到8/spl倍/10/sup -10/的水平。

Study of a 196.0 THz (1529 nm) frequency standard based on an optically pumped rubidium vapor

We study the performance-of 196.0 THz (1529 nm) DFB lasers frequency-locked to absorption lines of a rubidium vapor optically pumped at 384 THz (780 nm). We describe a simple theoretical model giving the absorption profile of such a vapor. The measured frequency stability of two DFB lasers frequency-locked to these lines reaches a level of 8/spl times/10/sup -10/.<>
