So finally after about a year on the back burner, I finally managed to get some time in on the LASER. I have been slowly acquiring bits for the re-build over the past year, but this is the first real hands on moment I had for a while. One of my more recent acquisitions for the LASER was a 100W power sensor for measuring the output power of the LASER. The idea being that I would use it to monitor the health of the tube and my optical path once I got everything up and running. I also wanted to have an idea of what the real power was of my “free” LASER that had been sitting around for about 3 years before I got my hands on it, and then another year now on my shelf. So while the LASER was relatively new before being relegated to the scrap heap, a lot has happened that could have resulted in a drop in performance of the LASER. I’ve herd stories of the glass tube LASERs dropping in power output, even if just sitting on the shelf for a while… So I’ve been wondering if the same is happening to my LASER.
