A thread would do but i'd wonder which section to search for it then.
Also, there's more than meets the eye while vaporizing. Energy is being absorbed, phychoactive molecules start boiling at different temperatures, phase changes affect energy levels... In LASER or near-LASER heating only a portion of the visible spectrum would be adequate, etc., etc...
You arent a qualified physicist, but I am, so let me tell you how this works........ Mr. Kitty here......
Energy is being absorbed everywhere. Congratulations on learning that e=mc2. All we are doing in a vaporizer is passing hot air over a colder surface to gain a reaction, that reaction is the the vaporization (aka boiling, but not technically), and the pressure from the air flow pushes the vapor into a chamber for consumption later.
The correction is with respect to the laser beams..... Technically a laser beam doesn't have a temperature since it is made of photons and not matter. Temperature is related to the average vibrational energy of the atoms in a chunk of matter. No vibrating atoms means temperature can't be measured. I've yet to see a vaporizer that uses a laser beam, the only one I know of that might fit the bill reasonably is the Arctic III by Wicked Lasers, its 1 watts of blue laser light.
It will also blind you in under 300 milliseconds if it flashes your eyes. Not even direct beam, just a reflection from a bright object it shines on or a window etc.......
The visible spectrum is still heat, so it is all adequate. You emit light right now, its called black body radiation, and its given off in the infrared spectrum. Ever hear of FLIR? It detects black body radiation.

Our eyeballs can only see a part of the spectrum, and its the part thats useful for is to reproduce in. We need to see objects, not infrared or xray photons.
