Abstract
We report an efficient conversion of multiple transverse mode output of TEA carbon-dioxide laser into the 5 micrometer region by second harmonic and sum frequency generation in wide- aperture long AgGaSe2 crystals. The second harmonic pulses with energy up to 350 mJ (at an external efficiency (eta) equals approximately 10%) and the sum-frequency pulses with energy up to 50 mJ ((eta) equals approximately 1.5%) have been obtained. The recent applications of this radiation are discussed.
