Hello everyone!
I am fairly new to laser (have been lurking for some time but still quite a noob I guess ) and I was wondering how powerful must a green laser be to view the dot on the clouds? I've read before that this is possible.
I currently have a 2W blue laser (bought it from Blord) but because of diffraction(?) the beam goes very wide and I can't see it on the clouds at night. I was able to spot the dot on trees about 1km further (while focused to infinity) but not on clouds.
So, now I want to buy yet another laser (the addiction has begun :drool but this time a green one, and it doesn't have to be nearly as powerful as my 445nm one
So, I found this laser on lazerer:
Focusable 50mw green laser pointer <== Clicky, it's a link!
Will this be strong enough? The site says they are guaranteed overspec so I guess that's good. Or should I stick to a slighty more powerful one from O-like? (Lazerer stock is very... empty right now )
Reading from this forum they both seem good manufacturers and the prices aren't too shabby (for 50mw up to 200mw that is ).
Can you laser-gurus maybe point me in the right direction? Thanks
