Hi everyone, first post!
I'm an art student interested in making some light sculptures using lasers and mirrors, and I'm having trouble finding what kind of laser it is I need- I want a laser which can be left on for long periods of time, ideally all day in a gallery space, so I guess it would need to be mains-powered? (if it's just an ~8hr battery that's also fine) I would prefer to buy a pre-made one but I'm not averse to putting one together if the process is well documented, my electronics skills are limited though. I would like it to be blue or green (blue is preferred if I can afford it) I also don't want to get something which is too powerful for my needs and a safety risk, but equally has enough power. So what kind of power would I need to make something with a beam reflected say 20 or 30 times (on front surface mirrors), in a 3m x 3m darkened space? Could I achieve that with a laser that is safe to walk through the beams? Alternatively I could buy several cheaper lasers which are less powerful and safer. The main stipulation here is leaving them on without overheating.
If you have any recommendations I would be grateful. My budget is £75/~$115 but I don't really know if that's possible. I'm UK based.
Thanks for your help!
