Thanks for the response. I took a look at Sanwu, and it looks like the cheapest 3W is $220, which I was kind of expecting, but hoping it would be cheaper. What's the difference between Single and Multi operational mode?

I'm looking for a laser pointer with a bit of oomph behind it. I currently own a 450nm (maybe 420) laser that was listed as 1000mw on eBay. I can burn stuff like electrical tape and wooden surfaces with it at close distances (up to about 4 ft). I've homemade some safety lenses out of some spare...

This is the acrylic I planned on using: https://jtechphotonics.com/?product=445nm-laser-shielding . Will this not work as eye protection or is it meant as basic shielding?

Just to clear up confusion: The <5mW green laser is broken and has been replaced by a 450nm (blue) laser. Link for the laser...

To make a long story short, I owned a green, <5mW laser pointer for pointing at stars and such. But it was in a cheap case so it broke after about a year. My grandmother wanted to replace it for Christmas, and I'm not sure what type of laser this is. I know for a fact that it's 450nm, but I'm...
