"The first to demonstrate coherent light emission from a semiconductor diode (the first laser diode), is widely acknowledged to have been Robert N. Hall and his team at the General Electric research center in 1962"

laser scalpels are common place now in many operations, as they cut the flesh and caurterise the wound to stop bleeding at the same time.

They have started using lasers for many medical practices. I have heard of testing lasers to clean teeth at dentists.

They are also use to burn... certain warts off.

The green beam, usually (set at around 50mW I think) has been found to stimulate healing for patients. This was found for things like athletic injuries or soreness... I'm not sure about other types of injuries... say from a bullet ;D

It's down to IR as well as other aspects of the laser. It's nothing new that you can get IR healers pretty cheap and use them to stimulate muscle pains and sores. A laser is far more concentrated. It's uses are pretty much limited to burning. With teeth it's used to burn away plaque.

Lasers also speed up the closure of a small open cut by using heat to speedup the clotting of platelets in the blood. This would be extremely painful unless practiced properly and by the right people (ie. not yourself).
