Widest visible beam? For red, green, blue lasers

[InfinitusEquitas]

It's about 500mW. The beam is about 2mm, divergence is ~1.5-1.8mrad.

It looks thicker than it is because in terms of perceived brightness... it's so much much brighter than the other lasers in the picture.

Thats the one i wana get. Best visibiliy, and a good burner i bet....I think blue is cool but that wide green beam is way too sick! $350 is too much for me to justify, maybe ill get lucky to find a custom build on here for less. I was told its aprox. $200 just to build my own blue, what would you recommend.?
Thanks

You can build your own, check out the Laser Pro Shop section of the forum, there are a ton of kit options.

You can also buy one through the forum on the b/s/t section. For 445nm you can get a nice laser and goggles for under $200.

For green, it will be more expensive though.
