Enhancement of efficiency in femtosecond optical parametric oscillators using group-velocity-matching in long nonlinear crystals
The authors describe the exploitation of group-velocity-matching in femtosecond optical parametric oscillators (OPOs) for enhanced down-conversion efficiency into the mid-infrared (mid-IR). We demonstrate the concept in a femtosecond OPO based on a long MgO:PPLN crystal, for the first time, by utili...
