Efficient generation of mid-infrared radiation in an AgGa(x)In(1-x)Se(2) crystal.
Efficient generation of mid-infrared radiation by noncritically phase-matched second-harmonic generation is demonstrated in a mixed chalcopyrite crystal, AgGa(x)In(1-x)Se(2), and compared with that in an AgGaSe(2) crystal. Nonlinear coeff icients d(36) of AgGa(x)In(1-x)Se(2) and AgGaSe(2) crystals have also been derived.
