摘要
在这项工作中,我们提出了一个工作在1.5 $\unicode{x3bc}$ m的高功率,高重复率的全光纤飞秒激光系统。该全光纤激光系统可以以10.6 GHz的基本重复率发送飞秒脉冲,平均输出功率为106.4 W -据我们所知,这是迄今为止报道的1.5 $\unicode{x3bc}$ m的全光纤飞秒激光器的最高平均功率。利用基于孤子效应的脉冲压缩效应和优化的预啁啾色散,放大后的脉冲在全光纤配置下被压缩到239 fs。在这种高功率超快光纤激光系统的支持下,我们进一步探索了LP01, LP11和LP21横向模式之间的非线性相互作用,这些模式有望在使用大模面积光纤的光纤激光系统中存在。从理论上研究了多模态调制不稳定性,并随后在我们的实验中确定了这种不稳定性。这种高功率全光纤超快激光器没有笨重的自由空间光学元件,预计将成为一种有前途的激光源,用于特别要求紧凑和强大的操作。

m. This all-fiber laser system can deliver femtosecond pulses at a fundamental repetition rate of 10.6 GHz with an average output power of 106.4 W – the highest average power reported so far from an all-fiber femtosecond laser at 1.5
$\unicode{x3bc}$
m, to the best of our knowledge. By utilizing the soliton-effect-based pulse compression effect with optimized pre-chirping dispersion, the amplified pulses are compressed to 239 fs in an all-fiber configuration. Empowered by such a high-power ultrafast fiber laser system, we further explore the nonlinear interaction among transverse modes LP01, LP11 and LP21 that are expected to potentially exist in fiber laser systems using large-mode-area fibers. The intermodal modulational instability is theoretically investigated and subsequently identified in our experiments. Such a high-power all-fiber ultrafast laser without bulky free-space optics is anticipated to be a promising laser source for applications that specifically require compact and robust operation.
