I just remembered, that was the laser that I was going to buy of you. I remember that picture. Such a large laser head.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Thanks Curtis, that thing lights up the whole room, everything turns green, if you look at the wall behind the laser, and the side of the humidifier, those are reflections from nearly 30' away!

I guess this would be a good time to turn everything green, since it is almost St. Patricks day!

Edit: @ Alaskan, no animals were injured in the process.

I see, yellow is so cool. How much power did you think you might try to get (I know, as much as possible and depends on the drive power).

A millimeter(mm) is a mm ?

They are talking about the diameter of the beam. You can see the difference in the pictures.

Get a metric system ruler and measure the diameter.

At same output power a 3mm is brighter than a 5mm. It is called power density---milliwatts per cm squared.
