Abstract
A method and an apparatus according to an embodiment includes a distal end portion of an optical fiber core having a multilayer dielectric coating. For side-firing optical fibers, the coating can be disposed on an angled surface at the core distal end to produce total internal reflection of laser energy at the angled surface. The coating can also be disposed on an outer surface of the distal end portion of the core. The coating and the angled surface can be collectively configured to redirect laser energy in a lateral or side-fired direction. For end-firing optical fibers, the coating can be disposed on an outer surface of the distal end portion of the core. The coating and a perpendicular surface at the core distal end can be collectively configured to direct laser energy in a direction substantially parallel to the distal end portion of the optical fiber.
