Thank you ecap. The problem was that in searching lasers for buy, i found only sites with no value of diameter, and i was wondering that was usance because the measurements they give was enough to understand the diameter with maybe some strange calculations. But was only a miss information of...

Wait the flapper flap my head with the blown bladder. I know some about wavelenght, but everywhere there are the same measurements - nm and milliwatt - and nobody say about the beam diameter. Thats the optical measurement i think, but seem nobody needs that value.

Sorry i'm most ignorant about lasers measurements... I search but i can't understand how is measured the diameter of the beams on lasers. Does the "nm" measure tell something about the diameter of the beam? Thank you

Hello, there is a table of optics or laser selling that can do a beam diameter of 0.001 mm - 0.00004 inches ? Or 0.01mm - 0.0004 inches? What is the minimum you know? Is the optics the way to make it thin, or need the laser to be tiny? Thank you
