Several laser designers have requested Scientific Materials Corporation (SM) to consider methods to achieve a cladding for Tm:YAG diode pumped laser rods. SM has looked at several mechanical methods and concluded mechanical systems are impractical. In the early 1960's the PI of this program developed techniques to grow overlays of sapphire on ruby. These rods were used to c-w pump ruby and they worked. This proposal extends that work to provide a homogeneous cladding for Tm:YAG laser rods. These rods should have the advantage of the earlier ruby rods; improved pump coupling, less thermal lensing, and reduced secondary modes.
