Composite Optical Vortices Formed by Collinear Laguerre-Gauss Beams
... Let us start with the simplest situation that we have found: 1 = +1 and 2 = +2. The calculations can be seen in Fig. 1, which displays in row (a) the intensity profile of the beam, and in row (b) the phase of the field. In both types of images we have deliberately discretized the gray scale to appreci ...

Laser beam profiler
A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles. No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
