The reason for the optical frequency doubling in the 70Ga2S3–30La2S3 glass is investigated. The tetragonal Ga6La10/3S14 phase due to crystallization of the glass is responsible for the frequency doubling. Dense and transparent Ga6La10/3S14 crystalline thin films have been prepared by means of the controlled surface treatment of the glass due to an ultrasonic surface treatment. The effective second-order nonlinear optical susceptibilities of the crystalline thin films are analyzed. © 1998 American Institute of Physics.
