Abstract

The mixed crystals of A^IIB^VI compounds are an important class of materials with a variety of potential applications in opto-electronics devices operating in the blue-green spectra¹ region^[1]. Although foe optical properties of Zn_1-xAg_xSe have been well established recently, little is known about their nonlinear properties as a function of Ag content. The band gap energy and lattice constant of Zn_1-xAg_xSe increase with Ag content, hence the nonlinear optical processes such as second-harmonic generation, two photon absorption and nonlinear refraction index can be modified^[1-2].
