title: Generation of tunable subpicosecond light pulses in the midinfrared between 4.5 and 11.5 microm.
abstract: Stable subpicosecond infrared pulses in the spectral region of 4.5-11.5 microm are generated by difference-frequency mixing in AgGaS(2). The system uses femtosecond pulses from a Ti:sapphire regenerative amplifier and from a tunable traveling-wave dye laser. The infrared pulses have a duration of 400 fs, an energy of more than 10 nJ, and a repetition rate of 1 kHz.
