摘要
构建了基于混合锁模机制的双向运转掺铒光纤激光器。激光器采用σ型腔,腔内无隔离装置,以反射式半导体可饱和吸收镜和非线性偏振旋转效应为混合锁模机制,通过精细调节聚焦到半导体可饱和吸收镜上的激光光斑大小和腔内波片的角度,实现了稳定的自启动双向锁模运转。激光器运转在孤子锁模状态,腔内双向运转的2个脉冲分别由2个偏振分束器耦合输出。输出的2个脉冲序列重复频率相同,为60.72 MHz;逆时针、顺时针方向输出功率分别为23.7 mW和1.3 mW,信噪比分别为67.5 dB和66.5 dB。逆时针、顺时针方向输出功率相差较大,这是由采用的锁模机制造成的。
Abstract
A bidirectional hybrid mode-locking erbium-doped fiber laser is constructed. The reflective semiconductor saturable absorber mirror and the nonlinear polarization rotation effect are employed as hybrid mode-locking mechanism in the σ-shaped cavity without isolation device. The stable self-starting bidirectional mode-locking operation is achieved by finely adjusting the laser spot size focused on the semiconductor saturable absorber mirror and the angle of intracavity wave plates. The laser operates in soliton mode-locking state, and the two counter circulating pulses are output by two polarization beam splitters, respectively. The repetition rates of two pulse trains are both 60.72 MHz. The output powers of counter clockwise light and clockwise light are 23.7 mW and 1.3 mW, and their signal to noise ratios are 67.5 dB and 66.5 dB, respectively. The difference between counter clockwise and clockwise output powers is large, which is caused by the mode-locking mechanism.
