Hamm, P.; Lauterwasser, Christoph und Zinth, Wolfgang (15. November 1993): Generation of tunable subpicosecond light pulses in the midinfrared between 4.5 and 11.5 Mum. In: Optics Letters, Vol. 18, Nr. 22: S. 1943-1945


Stable subpicosecond infrared pulses in the spectral region of 4.5-11.5 ,um are generated by difference-frequency mixing in AgGaS2. 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.
