An ultra-flat, high-power supercontinuum generated from a picosecond telecommunication fiber laser was presented. The pulse from a carbon nanotube mode-locked oscillator was amplified using an Er-Yb codoped fiber amplifier. The output of the system achieved an average power of 2.7 W, with the center wavelength at 1564 nm and a FWHM of 6 nm in the spectral domain. By passing this amplified high-power pulse through a 4.6 m highly nonlinear photonic crystal fiber, an ultra-flat supercontinuum spanning 1600-2180 nm is generated. And the average power of the supercontinuum achieves 1 W.
本文展示了一种由皮秒电信光纤激光器产生的超平坦、高功率超连续谱。来自碳纳米管锁模振荡器的脉冲通过铒镱共掺光纤放大器进行放大。该系统的输出平均功率达到2.7W，中心波长为1564nm，光谱域的半高宽为6nm。通过将此放大后的高功率脉冲通过一根4.6m长的高非线性光子晶体光纤，产生了一个覆盖1600 - 2180nm的超平坦超连续谱。并且该超连续谱的平均功率达到1W。
