ABSTRACT:
An apparatus and method of fabricating an tubular reflector for use in a laser. The tubular reflector is formed by first grinding smooth the inside surface of a round metal tube. The polished tube is inserted into an elliptical mold. The mold is then pressed to shape the round tube into an elliptical tube. Next the inner wall of the tube is coated with a highly reflective material. Finally, a light source and a laser rod are positioned in the tube such that after the light source is turned on, light is reflected off the reflective walls of the tube to the laser rod resulting in laser light emitting from the ends of the rod. It may also be preferable that the elliptical tube be formed by combining and bending two flat metal sheets.
