During the 4/9 committee meeting & maintenance we were able to determine that the laser tube in Big Thunder is almost out. Our gauge currently has it outputting somewhere around 65 watts of an expected 130, down from 90 of last month. Additionally, it was noticed that the optics are getting close to being significantly misaligned as well.
We’ve determined that replacing the laser tube is something that will need to happen sooner rather than later, given the falloff in power we’ve been seeing and the fact that the last replacement of the tube was (I believe) in 2019. To that end, I’ve put up an emergency maintenance day for this coming Thursday the 14th at 6:30pm to get that done. While we’re at it we can also re-align the optics, which will need to be done starting with the first mirror in the back of the system.
This is the first tube change since I’ve taken over the position of Laser Chair, and while I’m in the process of reading up how it works, if anyone out there has experience from changing the previous tubes, your help would be greatly appreciated.

PS: During this maintenance I’d also like to try and fix the autofocus on the Fusion. We have the replacement plunger and the new cable ready to go, and waiting on it doesn’t make sense anymore. So that’s also on the list of things to get handled that day.
