Laser resonator supporting a nondiffracting, azimuthally polarized mode

We analyze the lowest-order mode supported by a laser resonator containing an intra-cavity transmissive axicon using the Fox-Li iteration algorithm. Two configurations were considered. By proper choice of the cavity dimensions, the lowest-order mode is nondiffracting and azimuthally polarized. The mode pattern at the output coupler is a Bessel function of the first order.
