Partially Coherence Nondiffracting Beams

초록

Recently, various diffraction-free beams have been proposed and studied with some potential applications in mind. Needless to say, nondiffracting beams are of great use in transferring information or energy, moreover, they have also been proved useful in nonlinear optics. When Bessel beams, which are typically nondiffracting, are used in the second harmonic generation, the overall efficency can be incresed with some interesting physics involved.
