Abstract
The application provides a laser holographic processing device, comprising: a spatial light modulator arranged in a laser light path, the spatial light modulator being used for modulating a laser beam to form a first modulated light beam; a modulation element arranged in a propagation path of the first modulated light beam, the modulation element comprising a substrate and a conical hole arranged on the substrate, the radius and the depth of the conical hole being in a first curve, a second curve or a high-order nonlinear curve relationship; and a multi-degree-of-freedom bearing platform used for bearing the modulation element and driving the modulation element to translate and / or rotate in multiple directions. The laser holographic processing device provided by the application can effectively balance the durability and the functional integration characteristics by optimizing the quality of the laser beam through the spatial light modulator and modulating the conical hole in different positions and postures.
