ABSTRACT:
A method and apparatus for coupling high intensity light into a low melting temperature optical fiber which uses a high temperature, low NA optical fiber as a spatial filter between a source of high intensity light and a low melting temperature, low NA optical fiber. In an alternate embodiment, the spatial filter is composed of a fused bundle of optical fibers. The source of light may be a high intensity arc lamp or may be a high NA, high melting temperature optical fiber transmitting light from a remote light source.
