Amazing! :bowdown: :bowdown:

And what about birds, plastic bags... passing through the beam? It would blind a lot of people, we are talking about 10W of power.

:eek: A 10W green laser so close to the street??.If a random bird, animal, or something passes in front of the beam, what will happen? :wtf:

And the laser should not sound in outer space.

Is that necessary? It is clearly a laser, but for some reason, they don't go at the speed of light. :undecided:

Interesting information... And 500MW, that's pretty impresive :eek:

I collect Cubecrafts. They are tedious to make, but they look really cool !

I point to the sky with my lasers every night. And I always point to an abandoned building under construction at about 3 km away. I'll never get bored of that. And I still have my first keychain red laser btw. :yh:

But I'm talking about outer space, not about space as in earth orbit. Like the laser of the Death Star in Star Wars.

I did, and I didn't find one.

Many of my friends laugh at me for my laser hobby. They say they are simply expensive colored lights. And I don't know how to explain them my love for lasers :yabbmad: Should I find new friends or what?

Thats what I thought. :thinking: And I think it is the correct theory. I googled for a bit and I found this HowStuffWorks "Lasers in Space" So the LASER beam is not visible in a vacuum, and neither in space

This morning I had a doubt about lasers. If the laser beam is seen thanks to particles in the air, then, is the laser beam seen in outer space? :thanks:

Hello there! I'm new too.I've been interested in lasers for about 3 years,and I decided to join this community. GREETINGS FROM SPAIN!
