Tóm tắt

We present a fiber laser system that generates femtosecond pulses at 914 nm from a continuous-wave solid-state laser source and using Nd-doped fiber amplifiers. This femtosecond laser architecture without mode-locking is based on picosecond pulse shaping by an electro-optic modulator followed by a Mamyshev regenerator to shorten the pulses down to 8 ps. Additional spectral broadening by self-phase modulation results in an output pulse spectrum of 10 nm, allowing the generation of nearly transform-limited 230 fs pulses.
