采用压控再生锁模技术，首次实现了10 GHz掺铒光纤激光器的理想锁相环（PLL）工作。在自由运行条件下的再生锁模光纤激光器的重复率可以通过改变提供给PZT的电压以改变光纤腔长度来连续地改变。PLL操作通过将相敏误差信号反馈到PZT来实现。该信号是通过将激光器时钟信号与合成器信号混频而获得的。外部信号跟踪范围为40 kHz。
Ideal phase-locked-loop (PLL) operation of a 10 GHz erbium doped fibre laser has been achieved for the first time by using a voltage controlled regenerative modelocking technique. The repetition rate of the regeneratively modelocked fibre laser in a free running condition can be continuously varied by changing the voltage supplied to the PZT to change the fibre cavity length. PLL operation is achieved by feeding back a phase sensitive error signal to the PZT. This signal is obtained by mixing a laser clock signal with a synthesizer signal. The external signal tracking range is 40 kHz.
