Abstract

A laser surgical probe (10, 100, 200, 300, 310) is disclosed in which laser energy can be directed at an angle relative to the longitudinal axis of the probe. The probe includes a housing element (14), an optical waveguide (18, 118, 218, 318) and an optical element (22). The optical element has a diverter (62, 162, 262, 362) and an intensifier (63). The diverter (62, 162, 262, 362) redirects laser energy at an angle relative to the longitudinal axis and the intensifier (63) concentrates the redirected light beam. The optical element (22) optionally includes a collimator (182) which collimates the laser light beam prior to the redirection of the beam.
