Laser Seems to Be Weaker
1) Clean Parts
Make sure your lens, mirrors, and beam combiner lens are clean. Clean regularly to ensure maximum performance.
2) Check Mirror Alignment
Perform the 4 corner test to ensure that your mirrors are properly aligned. If not, then align your mirrors to improve laser output.
3) Check Beam Combiner
Beam combiner could be loose. See if it wiggles when you touch it. If so, snap it back into place and tighten the screws.
4) Check Laser Tube
If the mirrors are aligned and you’re still noticing decreased output performance, your laser tube likely needs to be replaced. Note that the tube will not suddenly stop working, but as the gases inside start to degrade, you’ll notice that the output gets weaker and weaker over time. We’ve observed this starting to happen after about 800 hours of intense laser usage (actual laser run time).
