Normal-dispersion fiber optical parametric chirped-pulse amplification

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 mu m and seed with a continuous-wave beam at 0.85 mu m, and are able to generate idlers at 1.3 mu m with durations as short as 210 fs or energies as high as 180 nJ.
