Abstract
We present a novel method for generating tangentially and radially polarized laser radiations by using two pairs of positive and negative axicons. Tangentially and radially polarized diode-pumped Nd:YAG hollow lasers were demonstrated respectively. At an incident pump power of 17.8 W, the output power of tangentially and radially polarized laser beam is 6.9 W and 8.6 W, respectively. Polarization purity of tangentially and radially polarized laser beam is 99.2% and 98.7%, respectively. The experimental results reveal that tangentially and radially polarized laser beams with high polarization purity can be generated by resonator cavity consisting of only axicons. To the best of our knowledge, this is the first time that the cylindrical vector laser beam was realized only by axicons.
