“…Figure 13 shows some examples of DOEs in a grating-based DNA chip structure, 73,74) dynamic holographic optical tweezer system, 75,76) and high-capacity multilayered diffractive optical data pickup device. 77,78) Diffractive optics also has many industrial applications, such as in a laser beam splitter/combiner, 79) Gaussian laser beam pattern generator, 80,81) and input/output beam coupler for optical fiber communication. 82,83) Some multiple beam splitters are useful in high-power laser material processing.…”
