Abstract

We measure the efficiency of converting high-power 15-fs 0.8-μm pulses to the mid infrared in GaAs and GaSe as well as the pulse duration and the spectrum of the infrared radiation that is produced. Free-carrier production limits the conversion efficiency in GaAs to approximately 5 × 10^-7, allowing us to produce 2.5-pJ, 30-fs pulses spanning the spectral range from 6 to 14 μm. In GaSe we obtain, in a moderately saturated regime, a conversion efficiency of 7.5 × 10^-5, limited by two-photon absorption, allowing us to produce pulses of 100-fs duration containing 10 nJ of energy.
