Abstract: This invention is directed to a novel, portable, self-powered laser alignment device which can simultaneously generate plumb, square and level laser reference points. The laser alignment device is comprised of a main body that is pendulously suspended from a unit housing. The main body is adapted to house a plurality of orthogonally oriented laser diodes that, when energized, produce a plurality of orthogonal output beams to allow the operator to easily mark plumb, square and level reference points. The laser alignment device is self-leveling, which eliminates the time consuming calibration previously required for instrument setup. The movement of the main body is dampened by use of a magnetic dampening system that is comprised of a non-magnetic metallic plate, which is passed through a permanent magnetic field. The housing of the laser alignment device contains the main body, the laser diodes, the dampening system and a power supply to energize the diodes.
