The authors report supercontinuum generation in an ultrafast laser inscribed chalcogenide glass waveguide. The waveguides were fabricated using a Yb:glass cavity-dumped femtosecond oscillator with 600- kHz repetition rate. The waveguides were pumped using an optical parametric amplifier tuned to 1500 nm with a bandwidth of 100 nm. The broadest resulting supercontinuum spanned 600 nm (at -15 dB points) from 1320 to 1920 nm. The supercontinuum was generated in the normal dispersion regime, enhancing stability, and exhibits a smooth spectral shape.
作者报告了在超快激光写入的硫系玻璃波导中产生的超连续谱。这些波导是使用重复频率为600 kHz的掺镱玻璃腔倒空飞秒振荡器制造的。波导由调谐到1500 nm、带宽为100 nm的光学参量放大器泵浦。产生的最宽超连续谱在1320至1920 nm范围内跨越600 nm（在-15 dB点处）。超连续谱在正常色散区域产生，增强了稳定性，并呈现出平滑的光谱形状。
