摘要: 利用自主研发的全光纤被动锁模激光器以及高功率光纤模场匹配器,将145 W的皮秒脉冲耦合进国产光子晶体光纤,实现了67.9 W的高功率全光纤结构白光超连续谱输出,光谱范围为500~1700 nm,10 dB光谱宽度大于1000 nm(泵浦波长除外)。整个激光器系统的光-光(半导体泵浦源输出激光-超连续谱输出激光)转化效率达到33.8%。Abstract: Using independently developed all-fiber passive mode-locked laser and high power mode field adaptor to couple 145 W picosecond pulse into photonic crystal fiber, we obtain a 67.9 W high power all-fiber white-light supercontinuum laser source. Its spectrum ranges from 500 nm to 1700 nm and 10 dB spectral width is over 1000 nm (expect pump wavelength). The optical-optical conversion efficiency (from the power of semiconductor laser pump source to the power of supercontinuum laser) of the entire laser system reached 33.8%.
