Abstract
This paper describes a method used to align a complex resonator using a wavefront sensor. A brief description of the optical resonator and the phase aberration caused by the resonator misalignment that most greatly degrades the beam quality of the device is followed by a discussion of a low power HF alignment laser injection technique that was used successfully to align the laser by imaging the output aperture to a wavefront sensor. The wavefront phase was displayed in isometric form on a quasi-realtime display in order to determine the alignment position of the resonator's key optical element. High power lasing test wavefront phase data confirms this method results in a well-aligned resonator.
