Abstract

A laser probe includes a cannula, at least one optical fiber positioned within the cannula, and a lens positioned within the cannula at a distal end of the fiber. The lens is adapted to receive a laser beam from the optical fiber at a proximal end of the lens and to transmit the laser beam towards a distal end of the lens. The laser probe includes an optical element configured coupled to the cannula by a brazed joint and to receive the laser beam from the distal end of the lens and emit the laser beam from the probe. The brazed joint may form a hermetic or liquid-tight seal between the optical element and the cannula.
