Infrared pulses of 1 picosecond duration tunable between 4 mu m and 18 mu m

The generation of infrared pulses via difference frequency mixing of Nd:glass laser pulses and infrared dye laser pulses is discussed. Tuning between 4 and 18 mu m is achieved by various combinations of laser dyes (dye No. 5 and A 9860) and nonlinear crystals (AgGaS/sub 2/ and GaSe). The energy of t...

Zusammenfassung:The generation of infrared pulses via difference frequency mixing of Nd:glass laser pulses and infrared dye laser pulses is discussed. Tuning between 4 and 18 mu m is achieved by various combinations of laser dyes (dye No. 5 and A 9860) and nonlinear crystals (AgGaS/sub 2/ and GaSe). The energy of the mid-infrared pulses is in the order of a microjoule; and the photon conversion efficiency is
