Abstract: The present invention relates to a laser surgery apparatus for contact laser surgery and to a method of using the laser surgery apparatus. The laser surgery apparatus (1) comprises a contact laser scalpel (3) for contact laser surgery, the contact laser scalpel (4) comprising an optical fiber (4) of IR laser radiation transmissive material and terminating at an optical fiber tip (5) having an exposed core region, and support means for holding said fiber and for positioning said scalpel (3). Said fiber tip (5) is tapered and disposed at a distal end of the scalpel (3) for contacting a tissue to be cut and comprises an uncoated contact surface (6) for transmit ting laser radiation and a guiding surface that is at least partially reflective to laser radiation and provided such that laser radiation guided by said optical fiber (4) to said fiber tip (5) will be at least partially reflected by said guiding surface and emitted through said uncoated contact surface.
