the laser output port is coaxial with the galvanometer input port
during installation;
（4）Check the focus position and confirm that the parameters used
are set to the best state of the laser;
（5）After the laser is used, the laser power will have a power
attenuation of less than 8%/year, which is normal.
（1）Check whether the laser and the power supply are grounded
correctly and whether there is strong current or strong magnetic
interference around the laser. If there is interference, it is
recommended to use the signal line with shielding function. The
strong current and weak current are routed separately. Based on the
principle of red light priority, if the interference causes the trigger of
Laser output is

red light, the laser will not be emitted;
intermittent
（2）Check that the parameters and configurations used are
consistent with the characteristics of the processed materials. For
materials with high reflectivity or high damage threshold (such as
ceramics), high peak power parameters and strong energy density
parameters are required for processing. Poor use parameters and
configurations will also cause intermittent light emission.
