Abstract

We demonstrate here high-efficiency self-frequency-shifted soliton generation in standard single-mode fiber (SMF). Pulse with 80.96-MHz repetition rate passing through a length of 5.5-m fiber, Raman soliton with an energy of as much as 4.8 nJ was generated by pump pulse with an energy of 5.7 nJ, corresponding to an efficiency of nearly 85 %. Wavelength shifting of Raman soliton is fully investigated by controlling the input pulse energy, fiber length, and polarization state, resulting over 440 nm wavelength tuning range 1600–2040 nm. As the length of SMF is shortened to 0.5 m, Raman soliton pulses with energy and pulse duration of 3 nJ, 80 fs at 1700 nm and 6 nJ, 75 fs at 1820 nm are generated respectively, and the output average power keeps stable with a root-mean-square value of 0.7 % in four hours measurement. The proposed demonstration provides an easy-to-build, stable, high efficiency tunable laser source for multiphoton imaging.

在掺铒光纤激光器系统中产生高效率自频移孤子

我们在此展示了在标准单模光纤（SMF）中产生高效率自频移孤子的过程。重复频率为 80.96 MHz 的脉冲通过长度为 5.5 m 的光纤，能量为 5.7 nJ 的泵浦脉冲产生了能量高达 4.8 nJ 的拉曼孤子，效率接近 85%。通过控制输入脉冲能量、光纤长度和偏振态，拉曼孤子的波长偏移得到了充分研究，波长调谐范围为 1600-2040 nm，超过了 440 nm。当 SMF 的长度缩短到 0.5 m 时，在 1700 nm 波长处产生的拉曼孤子脉冲能量和脉冲持续时间分别为 3 nJ、80 fs，在 1820 nm 波长处产生的拉曼孤子脉冲能量和脉冲持续时间分别为 6 nJ、75 fs，在四小时的测量中，输出平均功率保持稳定，均方根值为 0.7%。该演示为多光子成像提供了一种易于构建、稳定、高效的可调谐激光源。
