Abstract

We report on a Q-switched short-length fiber laser producing 100 W of average output power at 100 kHz repetition rate and pulse durations as short as 17 ns. Up to 2 mJ of energy and sub-10-ns pulse duration are extracted at lower repetition rates. This performance is obtained by employing a rod-type ytterbium-doped photonic crystal fiber with a 70 microm core as gain medium, allowing for very short pulse durations, high energy storage, and emission of a single-transverse-mode beam.

摘要

我们报道了一种调Q短长度光纤激光器，其在100kHz重复频率下产生100W的平均输出功率，脉冲持续时间短至17ns。在较低重复频率下可提取高达2mJ的能量和亚10ns的脉冲持续时间。这种性能是通过采用一种芯径为70微米的棒状掺镱光子晶体光纤作为增益介质来实现的，该介质能够实现极短的脉冲持续时间、高能量存储以及单横模光束发射。
