Formation of a laser beam with a doughnut intensity distribution

Journal Article:

Abstract

The conditions of the simultaneous generation of TEM01 and TEM10 modes forming a beam with a doughnut intensity distribution are investigated. In the case of a complete suppression of the TEM00 mode, the ratio of the intensity at the crest of the ring to the intensity at the ring axis reaches 200 and is limited by dispersion in the optical elements of the resonator. Operation with mutual locking of TEM01 and TEM10 modes has been achieved which is characterized by complete spatial coherence of the ring-shaped beam.
