A linear cavity picosecond Er-fiber laser, which was passively and harmonically mode-locked with SESAM, is demonstrated. The advantage of the proposed configuration is the fast tuning of the pulse repetition rate in the range from tens of MHz to 1 GHz, realized by varying the pump power without any additional adjustment of the polarization.

线性腔光纤激光器与SESAM谐波锁模

演示了线性腔皮秒皮秒Er光纤激光器，该激光器被SESAM被动和谐波锁模。所提出的配置的优点在于，通过改变泵浦功率而无需对极化进行任何额外的调整，就可以在数十MHz至1 GHz的范围内快速调节脉冲重复频率。
