Abstract
A laser marking device including an oscillating mechanism that enables the laser beams emitted from the device to be emitted in either a constant state or in a pulsed state to enhance the visibility of the laser beam in various lighting conditions. The oscillating mechanism modulates the power supplied by the power source into either a constant state or a pulsed state in order to send the power in that state to the laser generator, which consequently emits a laser beam in either a constant or pulsed state. In bright light conditions in which the beam is not readily visible, the beam can be emitted in a pulsed state to be sensed by a separate detector capable of detecting the pulsed beam from the device. The detector provides an indication to the operator of the position of the beam relative to the detector such that the operator can readily determine the location of the beam.
