Pulse control device and laser processing system

A laser processing system, for surface processing of a material to be processed, comprising:

• a pulse control device comprising:
• a plurality of pulse generation circuits configured to generate a plurality of pulse signals according to a plurality of pulse setting data, respectively, wherein each of the plurality of pulse setting data at least includes a pulse frequency;
• and
• a pulse delay adjustment circuit connected to the plurality of pulse generation circuits and configured to control an interval time between the plurality of pulse signals according to a reference signal, and outputting a plurality of adjusted pulse signals, respectively,
• a plurality of seed laser sources;
• and
• a plurality of seed laser drivers, connected to the pulse delay adjustment circuit, connected to the plurality of seed laser sources, respectively, and configured to receive the plurality of adjusted pulse signals, respectively, and drive the plurality of seed laser sources to output a plurality of pulsed light beams according to the plurality of adjusted pulse signals,
• wherein the reference signal is one of the plurality of pulse signals or a standard signal, and a duration corresponding to the pulse frequency in each of the plurality of pulse setting data is different from the interval time.
