That's what I thought because none of my lasers could stand up to the sun but I have also never had more than 200mW of 532nm
on a side not have you seen this -->

it's apparently a laser shined at a reflective mirror on the moon you can even see the reflection back :drool:

Very high humidity will do that. Also the laser beam is not in direct sunlight, the video is shot completely under tree cover... for the few seconds that it is in the sun, it is completely washed out. I'm sure there are also camera settings to play with to make the beam more apparent.

I think it's probably true. It's probably only 700mW, but that's a ton of power for a 532nm laser. Green is extremely bright to cameras and people.

It's a mixture of crap in the air, viewing angle, and shade. In most scenarios, this simply won't happen.

NOT !
Look into it a bit more and you will find out why.

That video is just more WL crap marketting. How many different things do you think were tried before someone finally managed to get that one "special" take of everything just right to get it looking good.
Show me the hundreds of other tries and how poorly they turned out I say.

Clearly photoshopped. The beam even goes beyond the laser aperture, nice.

There is no reflector or mirror on the moon , it's a Retroreflector and they sent light back in the same angle and not reflect like a mirror

It says in the text:
In this case, two beams were being used to track the position of NASA’s Lunar Reconnaissance Orbiter, one of my favorite space missions of all time (to see why, check out this gallery of images I posted recently).

If you search a little futher they say this about the image:

This photograph shows the Laser Ranging Facility at the Geophysical and Astronomical Observatory at NASA's Goddard Space Flight Center in Greenbelt, Md. The observatory helps NASA keep track of orbiting satellites. In this image, the lower of the two green beams is from the Lunar Reconnaissance Orbiter's dedicated tracker. The other laser originates from another ground system at the facility. Both beams are pointed at the moon -- specifically at LRO in orbit around the moon.

So no mention of a reflected beam or mirror on the moon... lol ;)

Loved the trojan horse ref InfinitusEquitas! :crackup: +1
