In this project, we will grow an innovative, coilable and true double-clad crystalline YAG fiber and investigate its application to high energy lasers. The grown fiber will have all the required properties: single transversal mode operation, coilable fiber (to~100 cm), low propagation loss (<0.003/cm), high absorption and emission cross-sections, high thermal conductivity, and high laser damaging threshold. In the Phase I stage, we will deliver two 100+ mm long fibers to the Army and conduct the proof-of-concept experiments to demonstrate the lasing operation of this fiber. A longer fiber (at least 1500 mm) will be grown and delivered to the Army in the Phase II stage. A multi-kilowatt level lasing operation will also be demonstrated in the Phase II stage. We will also seek for commercializing this technology and applying this small footprint, light weight, rugged, clad crystalline based high energy laser to both the military (such as destroying enemy target at the speed of light) and civilian (industrial manufacturing) applications.
