High-power difference-frequency generation at 5-11 µm in AgGaS<inf>2</inf>

Abstract

Efficient generation of high peak power and high average power difference-frequency radiation, continuously tunable over the range of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5-11 \mu</tex> m, has been achieved by mixing the Nd:YAG laser radiation with the output of an infrared dye laser pumped by the same Nd: YAG laser in AgGaS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . Peak pulse powers as high as 180 kW with an average power output of 14 mW were obtained around 6 μm.
