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...
