We have used injection locking to multiply the repetition rate of a passively mode-locked femtosecond fiber laser from 40 MHz to 1 GHz while preserving optical phase coherence between the master laser and the slave output. The system is implemented almost completely in fiber and incorporates gain and passive saturable absorption. The slave repetition rate is set to a rational harmonic of the master repetition rate, inducing pulse formation at the least common multiple of the master and slave repetition rates.
我们利用注入锁定技术将被动锁模飞秒光纤激光器的重复频率从40兆赫兹提高到1吉赫兹,同时保持主激光器和从激光器输出之间的光学相位相干性。该系统几乎完全由光纤实现,并包含增益和被动饱和吸收。从激光器的重复频率被设置为主激光器重复频率的有理谐波,从而在主激光器和从激光器重复频率的最小公倍数处产生脉冲形成。
