In this work, we present a fiber-based setup for femtosecond pulse generation at $\sim910 - 940\;{\rm nm}$ wavelength. Pump pulses from a Mamyshev oscillator with center wavelength at 1036 nm 1 ps duration are amplified and coupled into a photonic crystal fiber forming a soliton at 1051 nm. Due to the nonlinear four-wave mixing process, soliton pulses are converted to 910–940 nm with a few hundred femtosecond pulses with energy up to 0.7 nJ. The proposed design utilizes features of the Mamyshev oscillator, enabling a robust way of generating femtosecond pulses at $\sim910 - 940\;{\rm nm}$.

基于 Mamyshev 脉冲振荡器和光子晶体光纤中波长转换的 910-940 nm 飞秒脉冲光纤源

在这项工作中,我们提出了一种基于光纤的设置,用于在$\sim910 - 940\;{\rm nm}$波长生成飞秒脉冲。来自 Mamyshev 振荡器的泵浦脉冲的中心波长为 1036 nm 1 ps 持续时间被放大并耦合到光子晶体光纤中,在 1051 nm 处形成孤子。由于非线性四波混频过程,孤子脉冲转换为 910-940 nm,能量高达 0.7 nJ 的数百飞秒脉冲。所提议的设计利用了 Mamyshev 振荡器的特性,能够以稳健的方式在$\sim910 - 940\;{\rm nm}$ 处生成飞秒脉冲。
