Demonstration and selection of a single-transverse higher-order-mode beam with radial polarization.
Single-transverse higher-order radially polarized beams with multiple rings are selectively generated from a Nd:YAG laser cavity by using a reflectivity-modified and polarization-selective photonic crystal mirror. As predicted by theoretical analysis [A. A. Tovar, J. Opt. Soc. Am. A 15, 2705 (1998)], the intensity distribution and propagation characteristics of the higher-order radially polarized beams are expressed by a Laguerre-Gaussian formula.
