A regeneratively amplified picosecond Ti:sapphire laser was used to pump optical parametric generation/amplification in 7% MgO:LiNbO3 crystals. Mid-infrared pulses with a tunability between 2.6 and 4.5 μm and pulse durations of 2–3 ps were obtained by angle tuning. The maximum pulse energy was 17 μJ at 3.3 μm, corresponding to a pump-to-idler photon conversion efficiency of 18% for the amplification stage.
