The laser source has no beam output

1 The lasers not ready for working

This situation usually occurs during the step of start-up. The reason is the ambient temperature is low or the lasers is not used for a long time, resulting in a long preparation (periodization)time of the laser source.

The solution is as follows: Recover the laser source temperature to workshop temperature, preheat the laser source with 1% power for 5-10 minutes after 30s of start-up, and then increase the power gradually after laser beam emitting.

2 The circuit is damaged

It is necessary to wait for the laser source completely warm-up after switching on. Once it is ready, it can be applied to emit laser beam.

In the case of the operation is not conducted as per the preheat procedure and immediately get the lasers working with high power after switching on, it would easily result in the circuit chips to burn out.

3 Laser Gas leakage

1. Due to dust prevention measures were not taken properly, or the influence of other burned lenses on the beam path, cause the output mirror becomes contaminated and burned through, internal gas leakage. It often accompanied by phenomena such as cavity contamination and circuit chip burnout.

2. The front and rear end plates of the laser source were on impacted, causing the components to loosen and resulting in internal gas leakage.
