Multi-dimension beam shaping laser internal engraving system and process based on spatial light modulator

Abstract

The application relates to the technical field of laser processing, and discloses a multi-dimensional beam shaping laser internal engraving system and process based on a spatial light modulator, which comprises a heterogeneous node set and a control hub, the heterogeneous node set comprises a spatial light modulator and a plurality of physical entity nodes for calculating beam shaping phase graphs; the control hub obtains node parameters through a data preprocessing module, outputs a heterogeneous data base, performs feature filling through a dimension self-adaptive module, generates a binary online state mask vector, maps parameters into a feature matrix through a space-time alignment module, filters the feature matrix with the online state mask vector, outputs a joint space-time shared tensor, constructs a query, key and value matrix through a cross coding module, calculates and outputs a space-time entangled state feature vector matrix, maps the feature vector matrix into an action space through a strategy closed loop module, and generates a phase graph task allocation instruction. The application realizes computing power scheduling and outputs a control light modulator instruction.
