67.9 W high power all-fiber white-light supercontinuum laser source

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%.
