A repetition-rate-stabilized frequency comb ranging from the violet to the mid-infrared (0.4-2.4 microm) is obtained by phase locking a femtosecond Ti:sapphire laser and a synchronously pumped optical parametric oscillator to a common supercontinuum reference. The locking results have bandwidths lower than 3 kHz. By changing the locking frequencies, different relative and absolute offsets of the constituent frequency combs are achievable.
通过将飞秒钛宝石激光器和同步泵浦光学参量振荡器锁相到一个共同的超连续谱参考源，可获得重复频率稳定的频率梳，其范围从紫光到中红外（0.4 - 2.4微米）。锁定结果的带宽低于3千赫兹。通过改变锁定频率，可以实现组成频率梳的不同相对和绝对偏移。
