It is necessary to evaluate new laser materials with increased                  wall plug efficiency.  Currently semiconductor laser arrays hold                the potential to be effective optical pumping sources.  In order                to utilize the semiconductor arrays effectively it is necessary                 to have laser materials with longer upper level laser lifetime                  than the commonly used Nd:YAG laser.  This work will study the                  feasibility for the growth of ND:lanthanum fluoride crystals                    using the heat exchanger method. These crystals have shown a                    lifetime of 670 microseconds and interesting high temperature                   laser properties.  Emphasis will be placed on minimizing the                    contamination from the oxide and hydroxyl ions which is known to                degrade the optical quality of these crystals.  The grown                       crystals will be characterized for optical quality and laser                    performance.
