How to Solve the Unclear Marking of CO2 Laser Marker?

Mainly start from the following aspects:

1. Check whether the laser resonant cavity has changed. Fine-tune the resonant cavity lens to ensure that the output spot reaches a good state.

2. Measure whether the laser entering the galvo is off-center, and adjust the laser.

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

4. If the current is adjusted to about 20A and the light intensity is not strong enough, it proves that the krypton lamp has been aging, and it is urgent to replace the new lamp.
