Optical fiber laser and geometric coupler |
摘要 |
In an optical coupling system for a fiber laser, a cylindrical lens extends parallel to a number of aligned light sources and a series of aligned input ends of optical fibers facing the light sources. Output ends of the fibers pass light to a solid state medium in a laser cavity. A block with precision grooves holds the fibers to align them with the lens and the images of the light sources. The cylindrical lens is biaspheric with a longitudinal axis and two refractive surfaces whose axially transverse cross-sections follow paths other than the paths of a conic section.
