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 113.5 W, 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.
为了兼顾高功率处理和蓝光扩展超连续谱(SC)产生,采用高功率激光源泵浦长锥形光子晶体光纤。获得了输出功率为314.7 W、波长范围从390到2400 nm的超连续谱。波长低于960 nm的光谱分量占总输出功率的36.1%,超过113.5 W,光谱平坦度在16 dB以内。据我们所知,这是首次实现输出功率超过300 W的全可见光波长超连续谱覆盖。该结果使覆盖可见光范围的超连续谱输出功率提高了两倍。
