WebThis is why using diffractive optics for beam shaping is an ideal solution. DOEs are commonly used in laser hair removal, laser tattoo removal, skin resurfacing, skin rejuvenation, body countering, and many more. Beam splitting using DOE The operational principle of beam split- ter DOEs is quite straightforward. From a collimated input beam, WebFresnel-type diffractive optical elements (DOEs) for general beam shaping of monochromatic, spatially incoherent light are demonstrated. Direct and indirect methods, i.e., adding a lens' phase to the designed Fraunhofer-type DOEs, are used for the design.
