Abstract

Parametric frequency mixing in nonlinear crystals represents a widely applied technique to generate ultrashort pulses in the wavelength range between 1 and 10 μm [1,2]. In this paper, we present a novel parametric device to produce femtosecond pulses around 5 μm with a repetition rate of 8 kHz and a higher efficiency and stability than previously reported.
