# Laser devices and methods for laser metal deposition

## Abstract

The present disclosure relates to laser devices for laser metal deposition and methods for laser metal deposition. A laser device for laser metal deposition on a substrate is disclosed. The laser device comprises: a delivery opening for delivering a wire or powder metallic feedstock to the substrate; a laser beam source configured to fuse the metallic feedstock with the substrate, the laser beam source being configured to emit a laser beam of a first power; a plurality of cameras configured to record images of a region of interest; and one or more light sources configured to illuminate the region of interest. The one or more light sources are configured to illuminate with a power of a blackbody radiation emitted during laser metal deposition.
