我们展示了一个记录超过20 W的黄光倍频输出的一种新型的掺镱光纤光源。在1060- 1100 nm波长范围内的脉冲源通过SRS有效地移位到在1100- 1180 nm范围内的CW种子的波长。虽然脉冲宽度由脉冲源确定，但波长由窄带CW种子设置。扩展频率在单程SHG中加倍到黄色，915 nm泵浦转换为黄色的总效率超过25%。该方案可用于在560- 590 nm范围内产生可扩展的、高功率的、具有成本效益的光源。
We demonstrate a record of over 20W yellow light by frequency-doubling the output of a novel Yb-doped fiber source. A pulsed source in the wavelength range of 1060-1100nm is efficiently shifted by SRS to the wavelength of a CW seed in the 1100-1180nm range. While pulse width is determined by the pulsed source, the wavelength is set by the narrowband CW seed. The extended frequency is doubled to yellow in a single pass SHG with an overall efficiency of 915nm pump converted to yellow exceeding 25%. The scheme can be used to generate scalable, high-power, costeffective sources in the 560-590nm range.
