Ok i'm new to this site and for my senior project at school i want to make a 1w or 2w laser. Can anybody post any link with all the materials i need and places that sell them for cheap. Thanks for all your guys help.
This. Perhaps you should look into a 405nm. You can do some very neat things with this wavelength since it acts as a blacklight and a laser. You'd only need 50 mw or so and you'd be able to demonstrate all kinds of effects like charging glow in the dark materials or fluorescence of things.
Guys, I expect "Selena" is probably busy reading over the posts in the Tutorials section of the forum and probably isn't reading here right now.
Besides, johnpapalol has already helped her out with her project.
OMG, the skeptical side of me just thought of something terrible. WHAT IF they are the same person or partners, working together to create an innocent looking post from a GIRL OMG who needs some of us laser GUYS to help her out and then johnpapalolz comes on, and offers her just the help she needs - a link to a laser store. By golly, that solves everything!
Nah, she's probably reading tutorials right now. That's my guess...
