MACHINING PROCESSES USING A RANDOM TRIGGER FEATURE FOR AN ULTRASHORT PULSE LASER

A machining process, associated with a workpiece, may include controlling, by a control device, a pulse repetition frequency (PRF) of an ultrashort pulse laser. The PRF may be controlled to maintain a substantially constant distance, on the workpiece, between adjacent pulses on a path. The substanti...

Zusammenfassung:A machining process, associated with a workpiece, may include controlling, by a control device, a pulse repetition frequency (PRF) of an ultrashort pulse laser. The PRF may be controlled to maintain a substantially constant distance, on the workpiece, between adjacent pulses on a path. The substantially constant distance may be maintained despite changes in a speed of the path relative to the workpiece. An amount of energy of each pulse on the path may be substantially constant despite changes to the PRF associated with controlling the PRF.
