Numerical simulation shows that 250-fs laser pulses at 1.55 μm are generated from a beat-wave seeded optical paraKeywords: Beat waves; Comb likes; Fs laser pulse; Group-velocity mismatches; Numerical simulations; Optical parametric amplifications; Optical parametric amplifiers; Optical parametric oscillators and amplifiers; Optical pulse generation and pulse compression; Para Optical parametric oscillators and amplifiers; Optical pulse generation and pulse compression; Ultrafast processes200910.1016/j.optcom.2009.02.0452016-02-24
