hello all. I just wanted to post and declare that it is possible to build a laser without asking silly questions that could have been easily answered with some searching. I just successfully completed an m140 laser in a C6 host using nothing more than the search tools here. When I started thinking "I would love to build a laser!", instead of asking someone here to tell me how to do it, I researched and found out how. My point is over the past months I have been educating myself I ran across soooo many questions posted on LPF that could easily be answered by simple searches. So any newbies trolling around thinking the same thing I thought a couple of months back - you can do it if you spend some time educating yourself. That should be mandatory any way as I am in awe of the power a 1W 445nm laser has. It frightens me to think about some over zealous 12 year old wielding one of those with no respect for the damage that can be done to persons or property. NOT a toy people. Be safe!
