A hundreds of watt all-fiber near-infrared supercontinuum

摘要

A 200 W all-fiber near-infrared supercontinuum is achieved in a nonlinear fiber amplifier with all-normal dispersion master oscillator power amplifier configuration. The spectrum stretches from 1064 to 2200 nm with 10 dB width of 740 nm and 54.6% optical to optical conversion efficiency. Peak power is the predominant factor in the initial stages of spectrum broadening, and pulse width plays a key role in the final width of the supercontinuum.
