摘要

一个小的，真空的，压电调谐的法布里-珀罗腔被稳定使用商业铷振荡器。使用两个二极管泵浦Nd:YAG激光器测量和控制腔的共振;每个锁在一个模腔上。一旦控制腔共振作为激光的频率参考。为了测量激光频率噪声，将其中一束激光与来自同一系统的另一束激光组合在一起。两个激光器之间的拍频允许测量线宽，频率噪声和根艾伦方差的单个激光器。报告了这些数据，并与更详细的激光频率控制方案的结果进行了比较。

Frequency noise measurements of lasers locked to a rubidium mastered optical cavity

A small, evacuated, piezoelectrically-tuned Fabry-Perot cavity is stabilized using a commercial rubidium oscillator. The cavity's resonance is measured and controlled using two diode-pumped Nd:YAG lasers; each locked to a mode of the cavity. Once controlled the cavity resonance acts as a frequency reference for the lasers. To measure the laser frequency noise, one of the laser beams is combined with a laser beam from an identical system. The beat frequency between the two lasers allows a measure of the linewidth, frequency noise and root Allan variance of a single laser. This data is reported and compared to results from more elaborate laser frequency control schemes.
