I just hooked up my laser and in the test mode, I get a visible ray inside the tube but it does appear to have a hot spot near the output end and it looks like a short. I can't tell for sure and without enough experince I am hoping someone here has an opinion. Definately no output as a peice of paper is quite safe at the output end. Sorry for the poor quality
