Could anybody tell me if shining another laser (1.3w 445 and others) through an HeNe tube can damage it? thanks for any feedback.

this is a video of my new Siemens LGR 7621S HeNe tube. Yes, I really suck at filming/editing video. Also a good excuse to play dubstep. :yh: O4PbpEgbyyc BTW it sucks less when you play it at 480p

Hi I have become very interested in lasers and found that this could be a great hobby. I currently have a 5mw green laser. I almost bought a new laser from WL but I found this awesome place. I am hoping to build a blue laser and more in the future. This also seems like a good place to learn...
