1. A system for a laser peening application with a laser, the system comprising:
an enclosure having a laser configured to generate a laser beam, the enclosure having one or more compartments, the laser disposed in a first compartment;
an applicator device comprising a laser peening pen configured to apply the laser beam to a surface of a workpiece to perform the laser peening application, the applicator device configured to receive the laser beam from the enclosure, wherein the applicator device is positioned outside the enclosure of the laser; and,
a purge system comprising:
an enclosure separate from the enclosure of the laser;
a supply line connected to the enclosure of the purge system and the enclosure of the laser for supplying compressed air to a space within the first compartment of the enclosure of the laser to remove combustible gases contained within the first compartment;
a return line connected to the enclosure of the purge system and the enclosure of the laser for recovering compressed air and combustible gases from the first compartment;
a compressed air line connected to a source of compressed air configured to provide compressed air to the enclosure of the purge system.
