Abstract实验利用商品光纤飞秒激光器,自行构建了一套完整的光学频率梳系统,并获得了约30dB信噪比的系统频移(fceo)信号.实现了光频梳重复频率(frep)信号及系统频移(fceo)信号的高稳定度锁定,并通过实验验证了光频梳锁定的跟踪精度.基于此稳定光频梳完成了对1064nm碘稳频Nd:YAG固体激光器的绝对频率测量.实验结果表明,frep的跟踪精度在100s取样时间时优于3.7×10-14,测量得到的1064nm激光器绝对频率为:281630111757362Hz.这一测量结果与国际计量委员会(CIPM)给出的国际推荐值符合到不确定度之内.
An optical frequency comb is built by using a commercial femtosecond laser and signal-noise(S/N) ratio of the fceo signal is obtained to be about 30 dB.Its repetition rate frequency and offset frequency are highly stable and the tracking stability is verified.An absolute frequency measurement of a 1064 nm Nd:YAG laser is realized by using this stabilized optical frequency comb.The tracking stability of the repetition rate frequency is superior to 3.7×10-14 at 100 s and the absolute frequency of the laser is 281630111757362 Hz.The experimental result is in accordance with the recommended value by International Committee of Weights Measures(CIPM).
