The invention discloses a laser device with homenergic pulse waves and a synchronized motion. The laser device comprises a resonant cavity, a light beam on-off modulator, a light beam energy modulator, a light power sensor, a motion controller, a light feedback controller and a trigger controller, wherein the resonant cavity outputs a plurality of pulse waves with stable pulse width time and energy; the light beam on-off modulator selectively enables one of the pulse waves to pass through; the light beam energy modulator adjusts the energy of the pulse waves according to a power feedback signal; the light power sensor senses the energy and the pulse width time of the pulse waves; the motion controller provides working motion information; the light feedback controller outputs the power feedback signal to the light beam energy modulator according to the energy of the pulse waves and the working motion information; and the trigger controller measures the time difference of the pulse waves detected from trigger to the light power sensor and corrects the opening time point of the light beam on-off modulator. Therefore, the processing quality can be stabilized, and the laser device is applied to various laser industrial manufacturing procedures.
Description
technical field [0001] The invention relates to a laser device, in particular to a laser device which moves synchronously with equal-energy pulse waves. Background technique [0002] Laser has a wide range of uses, and can be used for marking, scribing, fracturing and other processing purposes in industrial applications. The design of laser processing devices for the above-mentioned purposes often lies in the pursuit of high-quality beam output from the laser resonator, and the pursuit of physical performance specifications of the laser. [0003] However, the excitation source in the resonant cavity must be adjusted from time to time due to power requirements, resulting in unstable thermal balance in the resonant cavity, and thermal drift of components in the resonant cavity, making the output energy of the laser unstable. [0004] Furthermore, the quality switch (Q-switch) in the resonant cavity adjusts the switching frequency according to the frequency of the output pulse...
