摘要

Second-harmonic generation (SHG) of CO_2 lasers has been investigated since the early 1970s, resulting in the development of a number of efficient nonlinear crystals. Among the most suitable candi- dates for laser systems one finds are AgGaSe_2, ZnGeP_2, CdGeAs_2, and AgGaS_2. For these crystals measured conversion efficiencies of fre- Quency doubling have reached levels of 35/100, while basic principles and Damge threshold of materials pose an upper limit well above that, at 50/100.
