摘要：

Generation of ultrashort mid-IR pulses spanning from 8.5 to 10.5 mu m with high energy (up to 4.5 mu J) was experimentally demonstrated through difference frequency generation in BaGa2GeSe6 crystal pumped by 100-fs 0.95-mu m Ti:sapphire laser pulses. Optical damage threshold and two-photon absorption coefficient were determined for this pump pulses. Frequency conversion efficiency reached 0.24% at 1.85 mJ pump pulse energy and was decreased at higher one. Estimations indicate that application of 15 mm in diameter wide-aperture BaGa2GeSe6 sample will allow one to increase pump pulse energy up to similar to 10 mJ, and to increase the mid-IR pulse energy up to 24 mu J at the same efficiency.
