Mid-infrared Bessel beams generation by subwavelength structure on quantum cascade laser
We proposed mid-infrared Bessel beams generation by subwavelength structure on quantum cascade laser. The result shows that the ring slit structure on the laser facet can realize zero order Bessel beam of first kind. Compared with Gaussian beam, the non-diffracting properties are demonstrated. The F...
