Subject of Research. This paper discusses numerical simulation of spiral beams. Spiral beams have been experimentally obtained with the use of liquid crystal spatial light modulators (LCD SLM). The ability of dynamical change for the laser beam parameters has been studied. Method. Spiral beams are traditionally obtained by means of static masks defining the amplitude and phase distribution of the beam. The paper deals with modernized method with the use of two LCD SLMs. Modulators form separately the amplitude and phase distribution of the laser beam. Main Results. Numerical modeling of space spiral beams with different amplitude and phase characteristics has been carried out with the use of VirtualLab 5.0 software package manufactured by LightTrans GmbH. Simulation results are compared to the results of a natural experiment. Experimental results are in good agreement with computer simulation. It is shown that LCD SLMs application gives the possibility for dynamical change of the spiral beam parameters, their structure and the dependence of rotation angle on the distance. Distribution phase inversion leads to a change in the rotation direction of the laser beam and, therefore, to a change in the direction of its orbital angular momentum. Practical Relevance. The use of spatial modulators makes it possible to change dynamically the beam parameters, including rotation direction change. The results can be applied for solution of problems related to laser manipulating of microparticles, as well as the problems of determining the phase inhomogeneities of transparent objects.

Keywords: LCD spatial light modulator, simulation, beam cross section rotation, dynamical change of parameters, spiral beam.
