Hello,
I have worked with full spectrum lasers but just bought a new chinese 100w laser. It has been working ok for a few weeks. Suddenly started hearing a popping sound, thought it was the beam hitting the glue spots in the wood. Then today, it started making a strange noise, I watched the back right side of the tube when I fire and it slowly lost its pinkish glow, I went around the the tube itself and had someone hit pulse, I noticed a spark coming from the wire that is around the tube. I Took some pictures, the laser is not firing, I turned it off and came to this forum for help. I have pictures, if anyone can tell me what to do next to fix this and if my tube is broken or if the wiring needs replacing or what to do. Thanks
