We demonstrate a tunable passively mode-locked fiber laser with a selectable repetition rate of up to 640 GHz. The mode-locking mechanism is based on dissipative four-wave mixing in combination with a programmable optical processor as the spectral filter. We achieve up to 20 nm wavelength tunability and present mode-locked operation at repetition rates between 40 and 640 GHz. Measurements of the power spectra using a cross-phase modulation technique confirm the mode locking.
我们展示了一种可调节的被动锁模光纤激光器，其重复率高达 640GHz。锁模机制基于耗散型四波混频，结合可编程光处理器作为光谱滤波器。我们实现了高达 20nm 的波长可调谐性，并在 40GHz 至 640GHz 的重复率下实现了锁模操作。使用交叉相位调制技术测量功率谱证实了锁模。
