Causes and Solutions ①Whether the laser resonator has changed. Fine-tune the resonator mirror to optimize the output spot. ②The acousto-optic crystal is offset or the output energy of the acousto-optic power supply is low. Adjust the position of the acousto-optic crystal or increase the working current of the acousto-optic power supply. ③The laser entering the… Continue reading Laser intensity drops, markings are not clear enough
