Abstract
The present disclosure describes a laser assembly. The laser assembly includes a support comprising at least one mounting groove. The laser assembly includes at least one laser mounted in the at least one mounting groove in a one-to-one correspondence. Each of the at least one laser includes a light emitting component configured to emit a light beam. A beam-shaping component is disposed at a light path of the light emitting component. The beam-shaping component includes a light incident surface disposed close to the light emitting component, the light incident surface is configured to transmit the light beam emitted from the light emitting component toward an opening of the mounting groove, and the light incident surface is configured to change a divergence angle of the light beam along at least one of a fast axis direction or a slow axis direction of the light beam.
