Vector vortex beams with on-axis polarization singularities, such as azimuthally and radially polarized (AP, RP) vector vortex modes, have provided tremendous fundamental sciences and advanced applications, owing to their unique polarization structures . In this presentation, We wil report on the first demonstration of the direct generation of AP and RP vector vortex modes from a diode-pumped Pr³⁺: YLF laser with an intra-cavity spherical aberration.
