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 galvanometer is off-center.
Adjust the laser.
④If the current is adjusted to about 20A, the light intensity is still not enough.
The krypton lamp is aging, replace it with a new one.
