An apparatus for transmitting laser light and redirecting the light
laterally relative to an axis of the apparatus includes an optical fiber
having both a core and a cladding surrounding the core. The optical fiber
terminates at a distal tip having a surface inclined relative to the axis
of the optical fiber. A tubular member surrounds the optical fiber at its
distal end. The distal end of the optical fiber has a portion opposing
the tubular member for being united to the tubular member. The distal
portion is joined to the tubular member by an intermediate material
selected to have an index of refraction matching that of the core and the
tubular member.
