Summary form only given. ZnGeP/sub 2/ is transparent between 0.7 and 12 /spl mu/m and possesses the highest (d/sub 14/=75 pm/V) nonlinearity of all commercially available birefringent nonlinear optical crystals. These properties are very attractive for traveling wave optical parametric generation using short pump pulses to produce tunable signal and idler pulses in the mid-infrared (MIR). Recently 1-ps short MIR pulses were generated with a ZnGeP/sub 2/ optical parametric generator (OPG) pumped between 2.9 and 3.5 /spl mu/m by a second OPG based on MgO:LiNbO/sub 3/. Going to shorter pump pulses increases the role of the group velocity mismatch (GVM) and requires shorter crystal lengths. Consequently the anomalous near-infrared (NIR) absorption near the band-edge becomes a less stringent limitation on the pump wavelength. We report for the first time to our knowledge on femtosecond operation of a ZnGeP/sub 2/ OPG.
