High-Order Bessel-Gaussian Beam and Its Propagation Properties

  • A high-order Bessel-Gaussian mode is introduced to describe hollow beams. The results for high-order Bessel-Gaussian beams propagating through lens focusing system and free space are derived in terms of Collins integral formula. The diffraction patterns and profile for high-order Bessel-Gaussian beams propagating through the above-mentioned optical systems are illustrated.
