“…Various output power and spectral band can be obtained by different combination of the pump laser and nonlinear media. As a result, it finds widespread applications in a variety of study fields, including communication [1], spectroscopy [2], environmental monitoring [3], geodetic measurements [4], remote sensing [5], biomedical imaging [6], and national defense security [7].…”

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.
