Transverse modes of plane-mirror waveguide resonators
- Laser Devices and Techniques Div., Royal Signals and Radar Establishment, Malvern (GB)
Large numbers of waveguide gas lasers (CO/sub 2/ ones especially) have found medical, military, industrial, and scientific application in the past few years. The simplest resonator design, with a plane mirror close to each end of a long thin dielectric tube, is still the most common. The authors examine what familiar first-order theory predicts about plane-plane resonator behavior, stressing the similarities and differences between circular-bore and square-bore devices. The effects of moving a mirror away from the guide are discussed, and illustrated with new results for the modes and losses of single-guide and U-folded designs with square bores. It appears that laser performance cannot be accurately predicted by previous treatments which use only a few (1-3) waveguide modes.
