Hello, now it's lasers I guess

With 9 stickys on conduct and usage I get the feeling "which lasers r gud?" Is a common theme that admins have gone to great lengths to mitigate, so with fair warning on how not to be that guy I figured I'd better say hello.

The last thing I need is another hobby, or even a project, but I got another hare brained idea that I can build a better mousetrap and since I have more money than sense I find myself in need of info pertaining to something I never took a natural interest in- lasers.

I promise to make liberal use of the search function and perhaps not even need to ask for guidance, but if I get stuck I'll post questions and hope for grace, as although I am capable of using logic I'm not techy so if you see me post please bare with me.

Thanks in advance
