I found this forum while researching lasers for about a week, and noticed you guys used a lot of the same technical components as flashlight enthusiasts. I guess this is the part where I talk about myself. :thinking:
I've been into lasers since the 1980s. For those of you familiar with the film "Real Genius", it won't be surprising. I lived a couple of years in Rochester NY and family and friends at Kodak and Xerox and lasers were pretty big back then. I used to follow all the reports on laser tests like the femptosecond lasers and the petawatt laser tests, and the 192 laser fusion experiments. I used to read all sorts of stuff on how lasers worked, and probably knew more 20 years ago than I do now about them. I played with them in highschool and competed in a physics Olympics. Before switching my major, I was going for a physics degree with a specialization in magnetohydrodynamics, and Hannes Alfven was my hero. For an astronomy class, I created a presentation on plasma, and touched briefly on lasers.
In Reality, I know almost nothing about lasers, primarily because I never had the funds to build them. I bought a tiny red laser while in Switzerland, and a tactical green laser in SanFrancisco for my friend, but the battery was dead so I had to partially disassemble it and tested it with a bunch of different batteries, until I got a very bright beam with a 9volt. I used to play with lines of batteries and capselas, and was familiar with overcharging flashlights till they burn out, so I figured it would be stupid to do that to an expensive laser, and we ended up buying new batteries for it, point is I have a lot to learn about lasers.
I'm still very new to these enthusiast batteries like the 18650 and A123 and have tons of questions. Like most people in post-wickedlasers times, I want to buy or make a >1000mw laser, but to be honest, my favorite colors are violet and tanzanite which actually ranges widely between what I'm guessing is 425nm and 465nm. I don't know how a fuchsia laser could be made since it's like red+violet, but I'd love to see a hot pink laser beam. I'm in my last courses at University right now so I'm about to have a whole lot of time and a bit of spare cash to invest in learning this stuff, and will probably take some electronic courses in the Fall or Winter. I know what a bread board is and built a crystal radio, but I don't really understand either. I'm also willing to travel great distances to learn.
I've taken a variety of shop classes including wood, metal, machine trades, drafting, and programming, and was once a blacksmith for night (have photos). I've got a huge interest in alloys like tungsten and aircraft aluminum, and recently wrote a paper on the former.
I guess that sums it up, apologies for the long winded intro.
