摘要: An optical gain-fiber of a fiber-laser or a fiber-amplifier is optically pumped by radiation from a plurality of external cavity, optically pumped, surface-emitting semiconductor lasers (OPS-lasers). In one example, radiation from the OPS-lasers is focused by a lens into cladding of the gain-fiber at one end of the fiber. In another example radiation from the diode-lasers is focused into the core of a delivery fiber at one end of the delivery fiber. The other end of the delivery fiber is coupled to the cladding of the gain-fiber.
