| Abstract Scope |
We have been developing laser gain media with composite structures and concentration gradients by transparent ceramics processing, where the “green body” is made by additive manufacturing (AM) techniques. Work has included laser rods with undoped endcaps and internal concentration gradients, thin disks with tailored gain profiles, and waveguide structures. The AM methods are direct-ink write and materials-jetting. The objective is to improve the overlap of the laser and pump modes, and to improve thermal management. Initial laser results on the manufactured parts will be presented. Our collaborators at Army Research Laboratory (Mark Dubinskiy, Team) and Radiation Monitoring Devices (Mike Squillante, Yimin Wang, Team) are gratefully acknowledged.
