1. An apparatus for applying laser to an object to remove coatings on its surface, comprising:
a laser module for generating and transmitting a laser beam and for deflecting and projecting said laser beam to the surface of said object, comprising:
a laser generator for generating a laser beam;
a laser scanner for deflecting and projecting said laser beam to said surface;
a laser beam delivery system for transmitting said laser beam from said laser generator to said laser scanner; and
one or more sources of cooling medium to cool some components of said laser generator, said laser beam delivery system, and said laser scanner; and
a robotic module for carrying and moving said laser scanner to reach the various areas of said surface;
a motion platform for carrying said laser module, said robotic module, and other supporting equipment and moving them around said object;
a fume extraction system for extracting and filtering by-products that are generated by the interaction between said laser beam and the coatings on said surface, comprising
a fume hood for containing by-products in the proximity where laser interacts with the coatings on the object;
a vacuum for sucking the air and particles from said fume hood and filter the captured matters; and
a hose for connecting said fume hood and said vacuum; and
a main computer interfaced with the laser module, robotic module, motion platform, and fume extraction system.
