Abstract:

First-surface roof-reflectors were constructed with apex angles near 90 deg and used as resonator elements in a 2-meter laser cavity with a gain medium of electrically excited CO2, N2, and He at 10 torr pressure. The divergence, far-field intensity distribution, and beat frequency components were measured for the output beams of several roof-resonator configurations. Both single-mode and multi-mode operation was achieved, and the mode structure of the several alignment-insensitive configurations was inferred. Author
