Abstract
A method for aligning the optical surfaces of a high extraction annular ring resonator which includes a scraper mirror with a decentered aperture. A probe beam is directed into the resonator cavity through the decentered aperture in the scraper mirror, and a visual and quantitative assessment of the amount of compact leg tilt and rear cone decentration is made. The optical surfaces are then repositioned into alignment based upon the results of the assessment.
