For a lens with positive SA, the maximum axial focused intensity is smaller and the focused beam radius is larger than for the no-SA case. The effects of the Fresnel number of the lens on the focused light intensity distribution are also discussed. It is noted that the smaller the Fresnel...
Numerical calculations are made and the results show that the PSA and NSA have a strong influence on the intensity distribution especially at the focus. The study showed remarkable results for which there is no hollow Gaussian beam at a large NSA along the optical axis at the focus. In ...

intensity distribution and angular spectrum of a Gaussian beam modulated by finite phase modulated defects has been derived.The impact of the modulation depth and the size of the defects on the intensity distribution and angular spectrum of the beam modulated by phase modulated defects is studied.It...
A generalized method for determining the properties of a Gaussian laser beam focus including waist radius, position, and intensity distribution is presented. Of significance to in situ laser diagnostic methods is a unique analysis of illuminated area as a function of intensity in a plane of the la...
The Gaussian beam intensity distribution is (42)I=I0e−r2/w2. [Note: It is common to describe a Gaussian mode of a laser by the electric field distribution E=E0e−r2/w02 and then give I=I0e−2r2/w02=I0e−r2/w0/22. The beam parameter w used in this treatment is the rad...
