在重掺钬光纤的基础上，首次提出并实现了利用光纤可饱和吸收体的全光纤调Q掺钬激光器。观察到两种振荡模式。其中一个允许一个获得脉冲的持续时间为20纳秒和峰值功率高达2千瓦。第二种模式类似于由簇内离子的相互作用提供的自脉冲。Q开关的类型由吸收体的长度决定。
For the first time we have suggested and realized all-fiber Q-switched Ho-doped laser with the fiber saturable absorber based on the heavily Ho-doped fiber. Two oscillation modes were observed. One of them allows one to obtain pulses with the duration of 20 ns and the peak power as high as 2 kW. Second mode is similar to the self-pulsing providing by an interaction of ions within the clusters. Type of Q-switching is determined by the length of the absorber.
