Method for crystal processing

A system for optical output regulation of a crystal, comprising a controller and machining equipment, wherein the controller is configured to:

• obtain an initial optical output value of one or more initial crystals;
• and
• determine a target optical output value of the one or more initial crystals;
• the machining equipment is configured to:
• determine an optical adjustment scheme for the one or more initial crystals based on the initial optical output value and the target optical output value;
• and
• perform surface roughness modification on at least one outer surface of the one or more initial crystals based on the optical adjustment scheme, such that an actual optical output value of the one or more initial crystals changes from the initial optical output value to the target optical output value, wherein surface roughness Ra of the at least one outer surface after the surface roughness modification is within a range of 0.001 μm-10 μm.

A method for crystal assembly, comprising:

• arranging a plurality of target crystals in an array to form a crystal array;
• wherein processing the plurality of target crystals includes:
• obtaining a plurality of initial crystals;
• determining an initial optical output value of each initial crystal in the plurality of initial crystals;
• determining a target optical output value corresponding to each initial crystal based on the initial optical output value of each initial crystal;
• determining an optical adjustment scheme for each initial crystal based on the initial optical output value and the target optical output value;
• and
• performing surface roughness modification on at least one outer surface of one or more initial crystals of the plurality of initial crystals based on the optical adjustment scheme, such that an actual optical output value of each initial crystal reaches the target optical output value corresponding to the initial crystal, thereby forming the plurality of target crystals.
