We propose a design of an all-fiber laser system that combines the most advanced Er:fiber laser in the telecommunication range and an efficient Yb-doped amplifier for generation of high-power ultrashort pulses. The system is based on nonlinear wavelength conversion of 1.56 μm ultrashort Er:fiber laser pulses to the 1 μm range in a short pigtail of dispersion-shifted silica fiber with subsequent amplification in the Yb-doped fiber amplifier. Pulses with a duration as short as 85 fs and averaged power of 200 mW are demonstrated.
我们提出了一种全光纤激光系统的设计，该系统结合了最先进的电信波段掺铒光纤激光器和高效的掺镱放大器，用于产生高功率超短脉冲。该系统基于在色散位移光纤的短尾纤中进行的 1.56μm 超短掺铒光纤激光脉冲的非线性波长转换，将其转换到 1μm 范围，然后在掺镱光纤放大器中进行放大。实验中得到了最短持续时间为 85fs、平均功率为 200mW 的脉冲。
