Abstract :
IR transparent bulk-crystallized chalcogenide glasses purely containing nontoxic and excellent nonlinear optical crystallites AgGaGeS4 were fabricated through careful ceramization process of the as-prepared glasses with the composition 53GeS2·47AgGaGeS4 at a temperature of 350 °C for various durations. The second-order optical nonlinearity of bulk-crystallized chalcogenide glasses was discussed on the basis of Maker fringe theory. A large second-order optical nonlinearity (for λ = 1064 nm) up to 5.79 pm/V, was evaluated in the IR transparent chalcogenide glass bulk-crystallized for 24 h.
