Abstract

In this study we demonstrate the suitability of Hollow-Core Photonic Crystal Fibers (HC-PCF) for multiwatt average power pulse compression. We spectrally broadened picosecond pulses from a SESAM mode-locked thin disk laser in a xenon gas filled Kagome-type HC-PCF and compressed these pulses to below 250 fs with a hypocycloid-core fiber and 470 fs with a single cell core defect fiber. The compressed average output power of 7.2 W and 10.2 W at a pulse repetition rate of approximately 10 MHz corresponds to pulse energies of 0.7 µJ and 1 µJ and to peak powers of 1.6 MW and 1.7 MW, respectively. Further optimization of the fiber parameters should enable pulse compression to below 50 fs duration at substantially higher pulse energies.

摘要

在本研究中，我们证明了空心光子晶体光纤（HC-PCF）适用于多瓦平均功率脉冲压缩。我们在充有氙气的 Kagome 型 HC-PCF 中对来自 SESAM 锁模薄片激光器的皮秒脉冲进行光谱展宽，并用准摆线芯光纤将这些脉冲压缩至 250 fs 以下，用单胞芯缺陷光纤压缩至 470 fs。在大约 10 MHz 的脉冲重复频率下，压缩后的平均输出功率分别为 7.2 W 和 10.2 W，对应脉冲能量为 0.7 µJ 和 1 µJ，峰值功率分别为 1.6 MW 和 1.7 MW。进一步优化光纤参数应能在更高的脉冲能量下将脉冲压缩至 50 fs 以下的持续时间。
