We report on a new design for a passively mode locked fibre laser employing all normal dispersion polarisation maintaining fibres operating at 1 μm. The laser produces linearly polarized, linearly chirped pulses that can be recompressed down to 344 fs. Compared to previous laser designs the cavity is mode-locked using a nonlinear amplifying fibre loop mirror that provides an additional degree of freedom allowing easy control over the pulse parameters. This is a robust laser design with excellent reliability and lifetime.
我们报道了一种新型的被动锁模光纤激光器设计，该激光器采用全正色散保偏光纤，工作波长为1μm。该激光器产生线性偏振、线性啁啾脉冲，可重新压缩至344 fs。与以前的激光器设计相比，该腔采用非线性放大光纤环镜进行锁模，提供了额外的自由度，便于控制脉冲参数。这是一种稳健的激光器设计，具有出色的可靠性和寿命。
