Název v původním jazyce

50-mu J level, 20-picosecond, narrowband difference-frequency generation at 4.6, 5.4, 7.5, 9.2, and 10.8 mu m in LiGaS2 and LiGaSe2 at Nd:YAG laser pumping and various crystalline Raman laser seedings

Popis výsledku v původním jazyce

A comparative study of picosecond mid-IR difference frequency generation in a wide wavelength range of 4.6-10.8 mu m in a simple down-converter based on the 8-mm long, high-damage-threshold crystals of LiGaS2 or LiGaSe2 under the 5-mJ, 20-ps, 1.064-mu m Nd:YAG laser pumping and the single-pass crystalline (CaCO3, BaWO4, CVD-diamond) Raman laser seeding was presented. 10-mu J-level, narrowband (<2 cm(-1)) generation at discrete wavelengths of 4.6, 5.4, 7.5, and 9.2 mu m with the optical frequencies equal to the vibrational Raman frequency or its second harmonic of various crystalline Raman seeders was demonstrated. Optimization of the pump spot and mode-matching between the pump and signal spots allowed to increase the output pulse energy up to 50 mu J in the case of LiGaSe2.
