Abstract
The generation of widely tunable ultrashort mid-infrared pulses with i ntensities sufficient for a substantial excitation of infrared states is discussed Single pulses of 1 ps duration and an energy of 7 mJ from an APM mode-locked Nd:glass laser with regenerative amplifier (repeti tion rate 4 Hz) serve as pump pulses. A three-path optical parametric generator pumped by the second harmonic of the Nd-laser produces tunab le near infrared pulses. Subsequent down conversion in GaSe provides p ulses of 0.7 ps duration tunable between 4 mu m and 20 mu m. Energies up to 25 mu J are measured.
