Abstract This study introduces a technique for generating stochastic electromagnetic (SEM) beams using a modified degenerate cavity laser in which one mirror is substituted with a spatial light modulator (SLM).We propose two methods to manipulate the spatial coherence of SEM beams: the Foot Care Treatments first involves adjusting the size of a spatial filter within the laser cavity, which alters the number of oscillating transverse modes and thus varies the spatial coherence.The second method employs phase modulation by applying a dynamic random phase to the SLM.This dual approach allows for precise control over the spatial coherence properties of SEM USB Type-C U Dock beams.
Experimental results demonstrate the generation of SEM beams using an SLM within a modified degenerate cavity laser and reveal a correlation between two orthogonal polarization components of the beams.
