title = "Experimental research on a ring beam with a phase-only spatial light modulator",
abstract = "Usually the intensity distribution of laser is Gaussian, but practical laser applications often require beam shaping. A ring-shaped pattern may be required in the confocal scanning microscopic imaging. Because phase-only spatial light modulators (SLMs) can be flexibly used to convert light wave fronts, the investigation of beam shaping by SLMs has become an active research area. In this paper, a phase-only liquid crystal spatial light modulator is used to transform a single-mode He-Ne laser into a ring-shaped pattern. This generated ring beam is investigated experimentally, and the experimental results with the pinhole size are analyzed.",
