Generation of 0.6 μJ pulses of 16 fs duration through high-repetition rate amplification of self-phase modulated pulses

Abstract

We have generated optical pulses of 16 fs duration in the submicrojoule range and at a repetition rate of 11 kHz. This was obtained by amplifying self-phase modulated pulses at the output of a fiber, using a couple of dyes to achieve gain covering a large spectrum around 620 nm.
