Tunable picosecond mid-infrared pulses generated by opticalparametric generation/amplification in MgO:LiNbO(3) crystals.
The Institute of Physical and Chemical Research (RIKEN), Hirosawa 2-1, Wako-shi, Saitama 351-01, Japan A regeneratively amplified picosecond Ti:sapphire laser was used to pump optical parametric generation/amplification in 7% MgO:LiNbO(3) crystals. Mid-infrared pulses with a tunability between 2.6 and 4.5 microm and pulse durations of 2-3 ps were obtained by angle tuning. The maximum pulse energy was 17 microJ at 3.3 microm, corresponding to a pump-to-idler photon conversion efficiency of 18% for the amplification stage.
