Fiber optic lasers and geometric couplers OPTICAL FIBER LASER AND GEOMETRIC COUPLER

摘要

In a fiber optic coupling system, a cylindrical lens extends parallel to a plurality of aligned light sources, and a series of aligned input ends of the optical fibers face the light source. The output end of the fiber passes light through the solid medium of the laser cavity. Blocks with elaborate grooves fix the fibers to align the image with the lens and the light source. A cylindrical lens is a double sphere with two refracting surfaces and a longitudinal axis so that the cross section in the transverse direction follows a different path than the path in the conical area.
