将可调谐连续钛宝石激光器锁定到由掺铒光纤激光器产生的自参考飞秒频率梳，从而产生单频光学频率合成器。该频率合成器的调谐范围为760-820 nm，绝对频率不确定度小于100 kHz。我们通过使用饱和吸收光谱仪测量85 Rb和87 Rb的D2线上的几个跃迁的光频率来证明这种连续光频率合成器的精度。
A tunable cw Ti:sapphire laser is locked to a self-referenced femtosecond frequency comb generated by an erbium-doped fiber laser thereby creating a single-frequency optical frequency synthesizer. This synthesizer has a tuning range of 760-820 nm with an absolute frequency uncertainty less than 100 kHz. We demonstrate the precision of this cw optical frequency synthesizer by measuring the optical frequency of several transitions on the D2 lines of 85Rb and 87Rb using a saturated absorption spectrometer.
