我们报告了一个高平均功率，平坦的超连续谱的产生使用紧凑的掺镱光纤放大器。由放大器传送的飞秒和皮秒脉冲耦合到两个不同的光子晶体光纤中。通过使用皮秒脉冲，获得了5W的最高输出功率，光谱范围从低于500nm到高于1800nm。数值模拟与实验光谱进行了比较，结果表明，即使是皮秒脉冲的展宽机制的主要部分是孤子效应。此外，二次和三次谐波过程导致一些尖锐的光谱线在可见光区进行了调查。(C)2003 Elsevier B.V.保留所有权利。
We report on the generation of a high average power, flat supercontinuum using a compact ytterbium-doped fiber amplifier. The femto- and picosecond pulses delivered by the amplifier are coupled into two different photonic crystal fibers. By using picosecond pulses the highest output power of 5 W with a spectrum ranging from below 500 nm up to above 1800 nm is obtained. Numerical simulations are compared with the experimental spectra and it is shown that the main part of the broadening mechanism is a soliton effect even for picosecond pulses. Furthermore, second and third harmonic processes leading to some sharp spectral lines in the visible region are investigated. (C) 2003 Elsevier B.V. All rights reserved.
