Abstract

We investigate the supercontinuum (SC) tailoring property by varying the transmission fiber length after the master oscillator power amplifier system. The conversion efficiency of the visible light band is effectively enhanced via tailoring the Raman extent of the injected 30 ps pulse into the nonlinear photonic crystal fiber (PCF). Experimentally, a 3.6 W all-fiber SC spanning from 414 nm to over 1750 nm (@20 dB) is accomplished by using a high duty cycle domestic PCF through precisely controlling the extent of Raman effect. The proposed method is instructive for the further realization of high power SC with an enhanced spectral intensity in the visible light band.

用不同的拉曼程度调整通过皮秒脉冲泵浦的瓦特级 SC 的可见光波段

我们通过改变主振荡器功率放大器系统后的传输光纤长度来研究超连续（SC）定制特性。通过调整注入非线性光子晶体光纤（PCF）的 30 ps 脉冲的拉曼范围，可有效提高可见光波段的转换效率。在实验中，通过精确控制拉曼效应的范围，使用高占空比国产 PCF 实现了 3.6 W 全光纤 SC，波长从 414 nm 到 1750 nm 以上（@20 dB）。所提出的方法对进一步实现可见光波段光谱强度增强的高功率 SC 具有指导意义。
