Research Institution
We propose to demonstrate that fine-grained polycrystalline Nd-doped YAG can be fabricated at low cost with optical properties close to those of single crystals. Its ease of fabrication in complex geometries makes it an ideal material of choice for solid state laser host material for use in Airborne Laser (ABL) and Tactical High Energy Laser (THEL) weapons systems. We will demonstrate that dense fine-grained polycrystalline Nd-doped YAG can be fabricated at low cost and that this material is fully transparent with inline transmission characteristics close to that of single crystals. Phase II will focus on scale-up and demonstration of performance as laser host material at levels of at least 53% optical-optical conversion efficiency with 500mW of continuous output centered at 1064nm wavelength.
