摘要
By using a photonic crystal fiber, a supercontinuum source with output power up to 1.7W, pumped by a passively mode-locked diode-pumped Nd：YVO4 picosecond laser is obtained. A spectral width of the supercontinuum is 1700 nm （500–2200 nm） with the 5 dB spectral width approximately 1000 nm （1200–2200 nm）. This high power wide band supercontinuum source meets the demand of many applications such as optical coherence tomography, frequency metrology and wavelength-division-multiplexing systems. The evolution of the supercontinuum with the increasing pump power is presented and analyzed.
