Not Available We propose to investigate the feasibility of manufacturing a simple waveguide laser that would demonstrate all of the qualities of fiber lasers while utilizing the simple pumping scheme of an side pumped Nd:YAG laser. The Phase I effort will involve modeling of the system and Phase II will be construction of a prototype. We will investigate a wound single mode rare earth doped fiber such that each new wrap of fiber is in the same plane as the previous wrap. The fiber would then be encapsulated with optical clear material and placed between two thin SiO (sub 2) substrates to create a wrapped fiber sandwich. To optically excite the active ions in the fiber's core, the sandwich would be pumped from the edge by a close-coupled laser diode bar. The outside of the substrate material could be silvered in order to prevent the pump light escaping. As the pump light passses through each wrap of fiber core, some about of it will be absorbed by the active ions creating the population inversion needed for lasing action in the fiber.
