RESEARCH ON OPEN RESONATORS. PART I: THEORY OF FLATROOF RESONATORS. PART II: EXPERIMENTAL TESTS OF MICROWAVE MODELS OF OPTICAL RESONATORS.
Abstract
A microwave or laser resonator with flat-roof mirrors is theoretically discussed. When the angle of the roof is extremely small, on the order of 0.001 radians for microwaves or 0.001 - 0.000001 radians for optics, this resonator has some features in common with the confocal resonator. A scaling method is applied to the study of the characteristics of a laser resonator. Experimental tests performed on a F.-P. resonator with plane square mirrors operating in the X-band are described. Measurements of frequency and quality factors of the resonator modes along with field distributions are reported and the results discussed. Particularly the close correlation between mirror deformations and field patterns is shown. (Author)
