*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, in the context of diffractive optics, refer to optical components that manipulate the phase, amplitude, or polarization of a light beam to achieve a desired output beam profile. These optics leverage the principles of diffraction to control and shape light in precise ways, allowing for tailored intensity distributions and phase fronts.
A beam splitter in the context of diffractive optics is a device that utilizes diffractive elements to divide a beam of light into two or more separate beams. Unlike traditional beam splitters that use partial reflection and transmission through materials like glass, diffractive beam splitters rely on the principles of diffraction and interference to achieve the splitting.
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.
