Abstract
The present disclosure includes systems and techniques relating to pulse laser printing. In general, in one implementation, an apparatus includes: a laser operable to produce a pulsed printing beam; an optics assembly operable to focus and direct the pulsed printing beam; and electronics communicatively coupled with the laser and the optics assembly, the electronics being operable to control the laser and the optics assembly to generate power pulses of the pulsed printing beam in synchronization with a series of moves that steer the pulsed printing beam in a non-raster scanning pattern to predefined locations on a material to alter an optical characteristic of the material at the predefined locations, which are arranged to form at least a portion of a symbol. The electronics may deliver the power pulses in synchronization with arrival at the predefined locations, and the electronics may be configured to receive sensed feedback in a closed loop.
