Photorefractive Materials and Their Applications 2 formatIsbn:Softcover - 9781441922243 first a comparison of differentIn this second volume of the book series devoted to photorefractive effects we focus on the most recent developments in the field of photorefractive materials and we highlight the parameters which govern the photoinduced nonlinearity. The availability of materials having the required properties is of major importance for further development of this field, and there are many parameters which have to be considered in the figure of merit of a
