Abstract

We generated subpicosecond pulses from 8 to 18 µm by difference-frequency mixing in a 1-mm-thick AgGaSe2 crystal, the 130- and 180-fs output pulses (1.45 < λ < 1.85 µm) from an 84-MHz-repetition-rate optical parametric oscillator. Numerical simulations show that intrapulse and interpulse group velocity dispersion determine minimum pulse duration above and below 15 µm, respectively. By cross correlation (upconversion) of 10.5-µm pulses with 90-fs, 810-nm pulses in AgGaS2, the pulse length was measured to be 310 fs in good agreement with simulations.
