So what kind of lazer makes a green beam? That would seem less than ordinary.

OTOH, cheap laser pointers can be had at any office supply store (most are red) and this could become more common.

Used mainly by astronomy lectures outside . great pointer at night.

Ok--so I go to Staples and get a laser...set myself up in the direction that the plane is landing and point away???

this is perplexing, it seems that it would be very difficult to actually get the laser in the cockpit window......

Why, a Green LASER of course!

That would be a YAG laser. I've got one. VERY bright and about 4+ times the power of a normal red laser. They have a range of two to three miles and are a lot of fun. Cost $89 and up.

There is even a cottage industry of modifying the things for power outputs in the 100+ milliwatt range.

Apparently a green beam works better than red or orange during daylight.

I have a green laser pointer.

Nothing cheap. There is a helium neon laser that is doubled for green but they are NOT that common, nor cheap. Cadmium Ion Argon lasers are green. But these are NOT the usual cat toys!

A green laser! They come in different wavelengths but the green ones are the best for zapping those pesky traffic cameras.

Spearmint?
