*Large-angle pattern that due to its symmetry properties is subject to geometrical distortion, if the DOE is used at laser wavelengths significantly different (Δλ > 50nm) from the design wavelength.
Beam shaping optics, especially those employing diffractive techniques, excel in enhancing laser machining, welding, and cutting by providing uniform energy distribution, resulting in cleaner and more efficient processes. In medical applications, they enable precise laser surgeries, such as LASIK, improving patient outcomes with minimal collateral damage. Additionally, they significantly boost optical communication by enhancing laser light coupling into fibers and managing modal dispersion, thus maintaining signal integrity over long distances.
Diffractive beam splitters excel in applications requiring precise control of light beams, compact and lightweight design, wavelength specificity, high efficiency, and versatile beam pattern generation. They are particularly valuable in laser systems, optical metrology, display technology, and spectroscopy, where their unique properties provide significant advantages over traditional beam splitters.
A diffractive pattern generator is a device or system that uses the principles of diffractive optics to create specific light patterns. Diffractive optics involves the manipulation of light through structures with dimensions comparable to the wavelength of light, typically using interference and diffraction effects.
