摘要

Two extended-cavity diode lasers at 780 nm which are longtime frequency-stabilized to Rb~(87) saturated absorption signals are reported.A high-performance frequency-locking circuit module using a first-harmonic detection technique is designed and achieved.Two lasers are continuously frequency-stabilized for over 100 h in conventional laboratory condition.The Allan standard deviation of either laser is estimated to be 1.3*10~(-11) at an integration time of 25 s.The system environment temperature drift is ...
