We have developed a chirped pulse amplification system for ultrashort 1300 nm pulses based on praseodymium-doped fluoride fibers (Pr:ZBLAN). The 1300 nm seed pulse is generated through soliton-dispersive wave coupling in a highly nonlinear fiber pumped by a pulse from an erbium-doped fiber laser. The seed pulse is stretched with a grating stretcher to ∼150 ps and amplified with a two-stage Pr:ZBLAN amplifier. The average power reaches ∼112 mW at the repetition rate of 40 MHz. The pulse is compressed to 225 fs by using a pair of gratings without serious phase distortion.
我们已经开发了一种基于掺镨氟化物光纤（Pr:ZBLAN）的超短 1300nm 脉冲啁啾脉冲放大系统。1300nm 的种子脉冲是通过在高非线性光纤中通过掺铒光纤激光器的脉冲进行孤子频散波耦合产生的。种子脉冲通过光栅拉伸器拉伸到约 150ps，并通过两级掺镨 ZBLAN 放大器进行放大。在 40MHz 的重复率下，平均功率达到约 112mW。通过使用一对光栅将脉冲压缩到 225fs，没有严重的相位失真。
