50-µJ level, 20-picosecond, narrowband difference-frequency generation at 4.6, 5.4, 7.5, 9.2, and 10.8 µm in LiGaS 2 and LiGaSe 2 at Nd:YAG laser pumping and various crystalline Raman laser seedings

50-µJ level, 20-picosecond, narrowband difference-frequency generation at 4.6, 5.4, 7.5, 9.2, and 10.8 µm in LiGaS 2 and LiGaSe 2 at Nd:YAG laser pumping and various crystalline Raman laser seedings

A comparative study of picosecond mid-IR difference frequency generation in a wide wavelength range of 4.6-10.8 µm in a simple down-converter based on the 8-mm long, high-damage-threshold crystals of LiGaS 2 or LiGaSe 2 under the 5-mJ, 20-ps, 1.064-µm Nd:YAG laser pumping and the single-pass crystal...

Zusammenfassung:A comparative study of picosecond mid-IR difference frequency generation in a wide wavelength range of 4.6-10.8 µm in a simple down-converter based on the 8-mm long, high-damage-threshold crystals of LiGaS 2 or LiGaSe 2 under the 5-mJ, 20-ps, 1.064-µm Nd:YAG laser pumping and the single-pass crystalline (CaCO 3 , BaWO 4 , CVD-diamond) Raman laser seeding was presented. 10-µJ-level, narrowband (
