Supercontinuum generation of 314.7 W ranging from 390 to 2400 nm by tapered photonic crystal fiber

To consider both high-power handling and blue-extended supercontinuum (SC) generation, a long-tapered photonic crystal fiber is pumped by a high-power laser source. An SC ranging from 390 to 2400 nm with 314.7 W output power is obtained. A spectral component below 960 nm accounts for 36.1% of the total output power, exceeding 113.5W, with a spectral flatness within 16 dB. To the best of our knowledge, this is the first time an SC coverage of all visible wavelengths with more than 300 W output power has been achieved. This result increases the output power of the SC covering the visible range by a factor of three. (C) 2021 Optical Society of America

Automated summary

By pumping a long-tapered photonic crystal fiber with a high-power laser source, a supercontinuum covering all visible wavelengths with an output power exceeding 300 watts was successfully achieved, with spectral flatness within 16 dB. This result indicates a threefold increase in the output power of the supercontinuum covering the visible range.
