Red lasers will not penetrate into tissue.  The higher wavelength, the more penetration you will have, with around 900 nm being optimum.

 

With lasers, there seems to be two ways of thinking.  Look at it like homeopathy or like physical modalities.  The 5 mw lasers provide a homeopathic dose, while higher powered lasers provide a physiologic dose.

 

Before you buy any laser, spend the money and buy Tuner and Hodes text on laser therapy.  Also go to www.laser.nu.

Steve,
Pulsed and non pulsed have completely different
effects on tissue. So you can't say that one is not
effective or the other is. It depends on what you want
to do. 635nm light has the ability activate all
biological light sensitive compounds called
chromophores in the body but does not have the ability
to produce heat that infrared does. Low power
(5mW)will not produce heat and is needed for
activation of the chromophores which, like your vision
is sensitive to not only not enough light but too much
is also sedating. Higher power, 30mW is needed to
penetrate deep into tissue and produce heat. This is
still a local thermal response where the low level 635
produces systemic activation to the body. 650 nm light
will miss many chromophores but be very activating for
others, unfortunately if that is on a fully collimated
laser, 40 mW will probably be too much power to
activate many of those chromophores. 650 nm will not
penetrate as well as infrared, above 760 nm light and
not produce as much heat either.

You are right about the confusion, even most
manufactures are confused. I of course am partial to
635nm, 5mW, fully collimated, laser light which is
pulsed accurately in excess of 1 MHz. Which is why I
built the LazrPulsr 4X with those parameters. I
believe this is the safest and most powerful therapy
of all known light units to date. Of course you need
to use the right frequency to pulse the laser to get
the results as frequency therapy is an exact science.

But all light therapy units have benefit and many have
hazards. Know what they are before you use them and
you will do great work.

There is a paper on my site, www.lazrpulsr.com on the
brochures page that will explain most of what you ask.
