报道了5W皮秒激光输出，脉冲宽度为30ps，重复频率为100MHz，经线偏振掺Yb光子晶体光纤（PCF）放大后输出功率为40.2W，斜率效率为58%。对应于43%的转换效率，实现了高达17.3W的二次谐波功率。
We reported the 5W picosecond laser with pulse width of 30 ps and the repetition rate of 100 MHz, which was amplified to 40.2 W with the linear polarized Yb-doped photonic crystal fiber (PCF), with the slope efficiency of about 58%. As much as 17.3 W second-harmonic power was achieved corresponding to the conversion efficiency of 43%.
