I have noticed that some lasers on the market (635nm healing lasers)
use a dot and some lasers use a line. I have heard it said that if you
are using a 5mw line then you are losing a significant amount of power.
For instance the Erchonia is said to only produce .6mw output of power
at the aperture. Wouldn't it make sense to just use 15-20mw diode (or
whatever it takes) until you arrive at the desired 5mw output at the
aperture for a line generated laser? Then you could cover more area in
less time with greater effect using a true 5mw. Just trying to arrive
at the bottom line of all this laser tech(pun intended).
