Interferometric generation of high order vector beams using an adjustable cat-eye cavity laser

we present an interferometric generation method of high order vector beams by using a cat’s eye cavity laser and a Mach–Zehnder interferometric arrangement, and various vector beams can be flexibly generated by adjusting the cat’s eye reflector and the optical wedges in the Mach–Zehnder interferometer. The basic theory of the generation method is introduced first, and then two kinds of high order vector beams based on the method are generated, whose intensity and polarization distributions of generated beams are further measured. The measured results verify the flexibility and efficiency of the proposed method, which may demonstrate unique advantages in some optical systems where different kinds of vector beams are required to use but no need to change the laser source.
