摘要We report 12.8 W supercontinuum generation with a high optical-to-optical conversion efficiency of up to 85% in an all-fiber device. This is achieved by using an all-fiber picosecond master oscillator power amplifier laser, which has an output pigtail double clad fiber, to pump a 3-m photonic crystal fiber with the core at one end enlarged by adiabatically collapsing two inner layers of air holes while keeping other holes open. Our experimental results show that the short-wavelength generation is due to dispersive wave trapping by redshifted solitons.
