A surgical laser tool comprising: an output member comprising: an output laser fiber having an exposed core at a proximal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the output laser fiber; a probe tip attached to a distal end of the output laser fiber, through which electromagnetic energy transmitted through the output laser fiber is discharged; and electrical contacts supported at the proximal end of the output member; an extension member having a distal end removably coupled to the proximal end of the output member, the extension member comprising an extension laser fiber having an exposed core at the distal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the extension laser fiber; and an optical coupler optically connecting the distal end of the extension laser fiber to the proximal end of the output laser fiber, the optical coupler comprising: a first ferrule supporting the distal end of the extension laser fiber and including a first ferrule end; a second ferrule supporting the proximal end of the output laser fiber and including a second ferrule end; and an adapter including a plurality of fins and a central bore that receives the first ferrule end and the second ferrule end, wherein the distal end of the extension laser fiber and the proximal end of the output laser fiber are supported by the optical coupler such that the longitudinal axis of the extension laser fiber is substantially coaxial to the longitudinal axis of the output laser fiber. an output member comprising: an output laser fiber having an exposed core at a proximal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the output laser fiber; a probe tip attached to a distal end of the output laser fiber, through which electromagnetic energy transmitted through the output laser fiber is discharged; and electrical contacts supported at the proximal end of the output member; an extension member having a distal end removably coupled to the proximal end of the output member, the extension member comprising an extension laser fiber having an exposed core at the distal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the extension laser fiber; and an output laser fiber having an exposed core at a proximal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the output laser fiber; a probe tip attached to a distal end of the output laser fiber, through which electromagnetic energy transmitted through the output laser fiber is discharged; and electrical contacts supported at the proximal end of the output member; an extension member having a distal end removably coupled to the proximal end of the output member, the extension member comprising an extension laser fiber having an exposed core at the distal end, the exposed core having a polished flat surface at a terminating end that is substantially perpendicular to a longitudinal axis of the extension laser fiber; and an optical coupler optically connecting the distal end of the extension laser fiber to the proximal end of the output laser fiber, the optical coupler comprising: a first ferrule supporting the distal end of the extension laser fiber and including a first ferrule end; a second ferrule supporting the proximal end of the output laser fiber and including a second ferrule end; and an adapter including a plurality of fins and a central bore that receives the first ferrule end and the second ferrule end, a first ferrule supporting the distal end of the extension laser fiber and including a first ferrule end; a second ferrule supporting the proximal end of the output laser fiber and including a second ferrule end; and an adapter including a plurality of fins and a central bore that receives the first ferrule end and the second ferrule end, wherein the distal end of the extension laser fiber and the proximal end of the output laser fiber are supported by the optical coupler such that the longitudinal axis of the extension laser fiber is substantially coaxial to the longitudinal axis of the output laser fiber.
