AbstractApplications of semiconductor lasers such as making a portable medical laser pack for field use require a compact power fiber- delivered light source. A problem with present fiber-delivered semiconductor laser sources is reliability, particularly at the fiber coupling or fiber connection areas where high optical powers can incinerate the connections. This proposal is for a feasibility demonstration of a fiber delivered source with emphasis on key optical connection technology. In Phase I we propose to use our existing 15 watt fiber-delivered sources to test detachable and replaceable fiber connections that potentially make these sources useful for medical applications. Phase II will develop and deliver complete sources to Phillips Labs, and extend present designs to higher powers. Our fiber's relatively low output divergence of under 30 degrees (measured to the 1/e2 intensity points) and small 400 um diameter permits high intensity focusing as well as low-loss power transmission over long distances.
