AI中文摘要：
本文报道并分析了在 silica 光纤中实现的创纪录的730nm参量转换，该转换从近红外波段延伸至短波红外波段。实验测得，1300nm信号（对应闲频光为2030nm）的参量增益超过30dB。此次转换采用行波单通单泵浦参量架构，通过高峰值功率与具有减小的四阶色散系数的非线性光纤相结合，实现了高效率。
英文摘要：
A record 730 nm parametric conversion in silica fiber from the near-infrared to the short-wave infrared band is reported and analyzed. A parametric gain in excess of 30 dB was measured for a signal at 1300 nm (with corresponding idler at 2030 nm). This conversion was performed in a travelling single-pass one-pump parametric architecture and high efficiency is achieved by a combination of high peak power and a nonlinear fiber with a reduced fourth-order dispersion coefficient.
