You wouldn't be able to see the laser, but if you got it on the right point:
THIS IS HOW MUCH LASER POWER YOU NEED!
Lasers can be shone onto the Moon because the NASA astronauts that landed there took mirrors with them. These mirrors reflect the laser light back to the Earth. Lasers are used to measure the distance to the Moon very accurately. If the time taken for the light from the laser to go to the Moon and back is carefully measured and the speed at which the light is travelling known, then the distance can be calculated.

So should I spend my pennies on a medium sized laser and a heyowge telescope or a BFO laser?
I'm leaning towards the 2nd option at the moment...
I've been looking at CO2 welding lasers .5KW should do it
but apparently they emit light in the infra-red spectrum so I won't be able to see it 
might be hazardous to passing aircraft too 
I like the warning on this site http://www.altair.org/CO2laser.htm
! ! DANGER ! !
Do Not Look Into Laser With Remaining Eye

Your first step would be to get a car number plate onto the moon. My laser pointer (Class 3a) picks 'em up at incredible distances!!!

Get a key ring laser and shine it through tha bottom of a milk bottle. This will magnify the laser and it will be mega. Make sure you dont shine it at any Astronauts eyes as this could blind them.
