Abstract
In 7.7 divided by 39.6 cm1 range investigated for the first time refraction and absorption spectra of AgGaSe2 and AgGa1- xInxSe2 crystals allowed to compute a phase matching characteristic and efficiency values of difference frequency generation with total laser intensity from 60 MW/cm2 up to 15 GW/cm2. The maximum efficiency values were close to 1*10-3. Powerful half-cycle pulse generation is proposed with the investigated crystals.
