Abstract
The reason for the optical frequency doubling in the 70Ga(2)S(3)-30La( 2)S(3) glass is investigated. The tetragonal Ga6La10/3S14 phase due to crystallization of the glass is responsible for the frequency doublin g. Dense and transparent Ga6La(10/3)S(14) crystalline thin films have been prepared by means of the controlled surface treatment of the glas s due to an ultrasonic surface treatment. The effective second-order n onlinear optical susceptibilities of the crystalline thin films are an alyzed. (C) 1998 American Institute of Physics.
