Abstract
We used the reflective phase-only liquid crystal spatial light devices to generate the higher-order Laguerre-Gaussian beams in experiment.Theoretically we caculated the optimal parameters for generating LG beams in detail and used MATLAB program to make Kinoform.We collected the date by CCD,observed the intensity patterns of the generated LG beams from plan wave and proved the spiral phase information by interferometry.We concluded a fit analysis of the radial profiles of the measured mode patterns and estimated the purity of the generated LG beams.
