Abstract
We demonstrate generation of two synchronized picosecond pulses at differen t wavelengths near 778 nm by frequency doubling of a femtosecond pulse. We use nonlinear frequency filtering with quasi-phase-matching gratings, which allow us to obtain second-harmonic spectral intensities that are higher th an the spectral intensities of the pump.
