Methods and apparatus for laser deposition

A method for laser deposition comprising:

• depositing at least one layer of material on a substrate using a laser deposition process that includes emitting a laser beam toward the substrate and injecting a stream of a powder material from a powder source into the laser beam using a deposition head that is connected to the powder source and is connected to a peen source;
• and
• shot peening the at least one layer of material by using the deposition head to propel a shot peen media from the peen source onto an exterior surface of the at least one layer of material after the laser deposition process has been halted.

A laser deposition apparatus comprising:

• a laser configured to generate a laser beam;
• and
• a deposition head configured to be fluidly connected to a powder source that contains a powder material and a peen source that contains a shot peen media, the deposition head comprising the laser, wherein the deposition head is configured to deposit at least one layer of material using a laser deposition process that includes emitting the laser beam toward a substrate and injecting a stream of the powder material from the powder source into the laser beam, the deposition head being further configured to shot peen the at least one layer by propelling the shot peen media from the peen source onto an exterior surface of the at least one layer of material after the laser deposition process has been halted.
