Question #: 6829

Question: What is a clear indication of a failing/failed laser tube? I know that laser tubes eventually "wear out", but how does one determine if the tube is loosing its "oomph"? My 40W Blacktooth laser tube return goes through an ammeter, so is the ammeter reading proportional to the beam strength, or can the beam die and still draw the same amount of current?

Current Solution

Dealing with glass co2 laser tubes, it is difficult to accurately tell if it is going out or loosing "oomph". The laser will loose its co2 levels, which will cause it to loose cutting strength.
We have noticed that the laser at its "strongest" or new state fires a purplish/reddish color laser through the tube, and when it is loosing its cutting strength it turns to a faded red orange/orange color.

Using a ammeter will only measure the current going to the tube. The PSU will not know when the tube is losing its cutting strength, so it will constantly flow the same voltage and current.
