All-fiber high-energy supercontinuum pulse generator



An all-fiber supercontinuum generator with a record-high pulse energy of 40 μJ is presented. The generator is based on a nanosecond ultralong high-energy mode-locked Yb-doped fiber laser with an additional amplification stage. The supercontinuum spectrum belongs to the wavelength range 500–1750 nm, and a relatively uniform spectral distribution of the intensity is observed in the interval 1125–1550 nm. The mean power of the supercontinuum is greater than 1.5 W. The simulation of such a generator yields the integrity of the supercontinuum pulse on the nanosecond time scale and shows that the pulse can be characterized by a certain energy in contrast to the multipulse complicated trains of supercontinuum corresponding to the femtosecond and picosecond pumping.
