What could happen when the laser tube is protected from overheat and how should it be handled?

If the laser tube gets overheat protection, it will stop working. When such a situation occurs, the user needs to do the following:

(1) Switch off the power supply of the laser.

(2) Check the chiller, whether the working condition is normal.

(3) Check the fan, whether it works normally

(4) Whether the fan and heat sink need to be cleaned.

(5) Whether the peripheral heat dissipation space for the air-cooling laser tube is sufficient.

(6) After eliminating the above possible failures, the user should wait for the temperature of the laser tube to be cooled down in the required range.

(7) Switching on the laser tube.
