Generation of a Purely Single Transverse Mode Vortex Beam from a He-Ne Laser Cavity with a Spot-Defect Mirror

Spot-defect mirrors were fabricated by focusing laser pulses on the surface of conventional dielectric mirrors. These mirrors were used as rear mirrors of a He-Ne laser cavity for generating a vortex beam. The intensity distribution of the beam generated from the cavity with a spot diameter of 50 𝜇m was in excellent agreement with theory. Comprehensive analysis of the intensity distribution, the beam quality factor, and the interference pattern revealed that the beam obtained was a purely single transverse mode LG01 beam.
