How to deal with the decline of laser intensity of marking machine

for some people who often use laser marking machine, the decline of laser intensity is a painful thing, which seriously affects the marking effect in the processing process and makes the mark not clear enough. In order to solve the problem of weak light intensity shown in the stimulated gracels experiment, we must check and repair the equipment

method 1: check whether the laser resonator changes, fine tune the resonator lens, and ensure that the lower pressure plate loads the sample upward under the action of the driving screw, and the output light spot reaches the best state

method 2: measure whether the laser entering the galvanometer deviates from the center, and adjust the laser

method 3: check whether the acousto-optic crystal offset or the output energy of acousto-optic power supply is low, adjust the position of acousto-optic crystal or increase the working current of acousto-optic power supply

method 4: if the current is adjusted to about 20a and the photosensitivity is still not enough, it proves that the krypton lamp has been aged and needs to be replaced urgently

like other machines, laser marking machines need operators to operate correctly and maintain well, so as to prolong the service life of laser marking machines and improve the marking effect
