摘要 为了控制和锁定飞秒激光脉冲的频谱,提出了一种相干解调的电路设计．该系统只采用一路光电探测信号,即可分别得到的重复频率信号和初始频率信号2个信息．实验中信噪比达到20dB．对于进一步控制飞秒激光频梳提供了便捷良好的方案． A coherent demodulated circuit has been designed to control a spectrum generated by a frequency stabilized femtosecond laser. In the circuit, the frequency repetition rate which was about 90 MHz and the offset frequency which was about 10 MHz by using only one photoelectric receiver were obtained. SNR of the output signal reached 20 dB in the experiment. This result provided a convenient and significant method for farther control of a femtosecond laser.
