Spectrum of spatial frequency of terahertz vortex Bessel beams formed using phase plates with spiral zones
... In the real experiment, the spiral phase plates were exposed to a Gaussian beam of the Novosibirsk free electron laser I : exp(2r 2 / w2 ) with w = 15.1 mm. The radiation intensity distribution along the Bessel beam and in the area behind a TPX lens with a focal length of 50 mm or 100 mm was record ...
