Abstract

Wave optics calculations for power losses and mode profiles of off-axis positive branch and negative branch unstable resonators have been investigated. The beam modes become fully one-sided with moderate power losses by shaving one side of the front mirror by 70% to 90% for a positive branch unstable resonator, and by 33% (=(|M|-1)/|M|) to 80% for a negative branch unstable. At the conference, we also discuss the advantage of negative branch unstable resonators for the applications to high-power lasers.
