High-gain fiber, optical-parametric, chirped-pulse amplification of femtosecond pulses at 1 (mu)m

摘要

Fiber-based optical-parametric chirped-pulse amplification is reported at 1 (mu)m in a microstructured fiber in the femtosecond regime. The signal has been highly stretched by an Offner triplet and then amplified with an all-fiber, pulsed-pump, fiber optical-parametric amplifier. More than 30 dB gain has been achieved over 8.3 nm, and the amplified signal has been recompressed.
