This Small Business Innovation Research (SBIR) Phase II project aims to develop and commercialize a unique class of laser and nonlinear optical crystals for application in telecommunications, materials processing, optical computing, medicine, and food safety. The goals of the Phase I Program were met, and as a result, a promising class of materials with many potential commercial applications was developed. In Phase I the feasibility of the approach was demonstrated by identifying crystal-growth procedures for several derivatives, evaluating their crystal structures, and studying their optical properties. Finally, we modeled their optical properties and predicted performance as both laser-host and NLO materials. As a result, we have identified the following candidate materials for further development in a Phase II program. The objective of the Phase II program is to apply the knowledge gained in Phase I to further develop crystal growth procedures to produce crystals of quality for incorporation into prototype devices, in preparation for Phase III commercializertion. We believe that a new class of optical products will be developed with significant commercial potential.<br/> Successful completion of the Phase II Program will lead to the development and commercialization of a unique class of laser and nonlinear optical crystals for application in telecommunications, materials processing, optical computing, medicine, and food safety.
