Paper Abstract

A shape-free coupling hole type laser is proposed to extract and transmit various output patterns by using the coupling hole mirror having an arbitrarily shaped hole. This configuration is demonstrated by combining a slow axial flow CO2 laser with two types of coupling mirrors having two holes or a ring-shaped hole. Two different coupling hole mirrors are fabricated by evaporating gold film on the ZnSe substrate onto which the masks for the coupling hole are attached. The lasing output is successfully obtained along with the pattern transmission characteristics.
