The mixed crystal system Y3AlxGa1-x5O12 was investigated at a laser host material for Nd3. Spectroscopic studies established that at the optimum composition a reduction by a factor of 3 in gain, as compared with YAlG Y3Al5O12, is possible, and implying increased output energy in Q-switched operation. Mechanical and thermal properties were found to be similar to those of YAlG. Laser rods were fabricated from boules of the material, examined for optical quality, and tested under Q-switched conditions. It is concluded that although the mixed crystal material has potential advantages, it is not possible to realize this potential because of the difficulty of growing crystals of high optical quality.
