We demonstrate the generation of a collimated hollow beam of variable diameter using a pair of convex and concave metal axicon mirrors. Using these homemade inexpensive convex and concave metal axicon mirrors of equal cone angle, we have generated a good quality hollow beam with high conversion efficiency (approx 76percent) from a Gaussian input beam. The focusing of the generated collimated hollow beam has been compared with that of a diverging hollow beam.
