We demonstrate a fiber optical parametric chirped-pulse amplifier pumped in the normally dispersive regime. This approach is readily scalable, offering a route to microjoule-level, femtosecond pulses at new wavelengths. As a first demonstration, we pump with chirped pulses at 1.03 μm and seed with a continuous-wave beam at 0.85 μm, and are able to generate idlers at 1.3 μm with durations as short as 210 fs or energies as high as 180 nJ.
我们展示了一种在正常色散区中被泵浦的光纤参量啁啾脉冲放大器。这种方法易于扩展,为新波长的微焦耳级飞秒脉冲提供了一种途径。作为首次演示,我们用 1.03μm 的啁啾脉冲泵浦,用 0.85μm 的连续波光束种子,并能够产生持续时间短至 210fs 或能量高达 180nJ 的 1.3μm 的闲频光。
