Abstract

We demonstrate an Yb:KGW femtosecond solitary mode-locked laser oscillator, which is used as a pump source for tapered fibers to generate white-light laser pulses with an average output power of up to 2.5 W and a spectral bandwidth of over 1000 nm. By spectrally filtering these pulses and subsequent compression of the filtered pulses with a prism sequence, we are able to generate ultrashort laser pulses with durations between 26 and 65 fs that are tunable from 600 to 1450 nm and with tens to several hundreds of milliwatts of average power.

摘要

我们演示了一种掺镱的 KGW 飞秒孤子锁模激光器振荡器，它可用作锥形光纤的泵浦源，以产生平均输出功率高达 2.5 W、光谱带宽超过 1000nm 的白光激光脉冲。通过对这些脉冲进行光谱滤波，并随后用棱镜序列对滤波后的脉冲进行压缩，我们能够产生持续时间在 26 和 65 fs 之间、从 600 到 1450nm 可调谐、平均功率为几十到几百毫瓦的超短激光脉冲。
