报道了2.7 μm氟锆酸盐光纤激光器的被动调q锁模工作。利用InAs薄膜作为可饱和吸收剂，实现了锁模和q开关。另一种使用的技术是所谓的飞镜锁模，即用带有振动镜的外部谐振器与有源光纤谐振器耦合。这两种技术都产生了q开关脉冲，其中包含持续时间短于2.5 ns的锁模脉冲序列，这是检测单元的分辨率极限。
Abstract Passive Q-switched and mode-locked operation of a 2.7-μm fluorozirconate fiber laser is reported. Both mode-locking and Q-switching were attained by means of InAs epilayers used as saturable absorbers. Another technique used was the so-called flying-mirror mode-locking, whereby an external resonator with a vibrating mirror is coupled to the active fiber resonator. Both techniques yielded Q-switched pulses containing trains of mode-locked pulses with durations shorter than 2.5 ns—the resolution limit of the detection unit.
