Paper Abstract

A pattern transmitting laser is proposed to extract and transmit arbitrarily shaped beams by using coupling-hole mirrors having various shaped holes. This configuration is demonstrated in a slow axial-flow CO2 laser. As simple examples the coupling mirrors with two holes and a donut (or ring)-shaped coupling-hole are fabricated by evaporating gold film on the ZnSe substrate onto which the circular masks or ring-shaped mask for two holes or a ring shaped hole are attached. The oscillation output from the two holes or ring- shaped hole is successfully obtained and the transmission characteristics are investigated. Image transmission is also demonstrated using a lens system composed of two Fourier transform lenses.
