Abstract: A method and an apparatus according to an embodiment of the invention includes a reflector disposed within a capillary for use in side-firing optical fibers. An outer member or cap can be used to protect the capillary when being inserted through a catheter or endoscope. The endoscope is then at least partially inserted into a patient's body to provide laser-based medical treatment. In some embodiments, a multilayer dielectric coating can be disposed on an angled surface of the reflector. In other embodiments, a multilayer dielectric coating can be positioned between a distal end surface of the reflector and an inner side of a distal end portion of the capillary. The coated reflector can be configured to increase laser energy redirected from a first portion of an optical path to a second portion of the optical path that is non-parallel to the first portion.
