Abstract
As other semiconductor lasers, concentric-circle-grating, surface-emitting lasers are compact, light, and efficient. However, unlike other semiconductor lasers, they emit high-power, low-divergence azimuthally polarized J1 Bessel–Gaussian beams. Because of their azimuthal polarization, they have a null at the center of the beam that makes them undesirable for certain applications. Binary phase compensation, a lossless technique previously used to improve the far-field profile of linearly polarized Hermite–Gaussian beams, is adapted to these azimuthally polarized beams to rid them of their axial nulls and improve their beam profile.
