Abstract: Methods include directing a laser beam to a target along a scan path at a variable scan velocity and adjusting a digital modulation during movement of the laser beam along the scan path and in relation to the variable scan velocity so as to provide a fluence at the target within a predetermined fluence range along the scan path. Some methods include adjusting a width of the laser beam with a zoom beam expander. Apparatus include a laser source situated to emit a laser beam, a 3D scanner situated to receive the laser beam and to direct the laser beam along a scan path in a scanning plane at the target, and a laser source digital modulator coupled to the laser source so as to produce a fluence at the scanning plane along the scan path that is in a predetermined fluence range as the laser beam scan speed changes along the scan path.

Abstract: In an example, a laser system receives an externally generated single command. The single command may be selected from a set of commands usable to control a laser diode driver of the laser system. The laser system may determine whether to select a group of one or more commands from the set of commands. In response to a determination to select the group of the one or more commands from the set of commands, the laser diode driver may be controlled using the one or more commands of the group.
