Abstract
An input coupler consisting of an array of conducting rings on a ZnSe substrate has been used in an optically pumped formic acid laser opera ting at 433 mu m. By using a uniform pump beam of optimized diameter a higher conversion efficiency than obtainable with hole input coupling has been achieved.
