A high-power ultraflat near-infrared supercontinuum (SC) is generated in a section of photonic crystal fiber (PCF) pumped by an amplified spontaneous emission (ASE) source instead of continuous-wave (CW) and pulsed lasers. A low-power ASE seed at 1 μm is amplified to be 90. 9 W by two fiber amplifiers and then emitted from a 10-μm-core fiber. https://www.chiggate.com/color-charm-050-cooling-violet-supply/
