Which lasers can be used in medicine?

Examples of lasers which can be used in medicine, both for surgery and therapy:

Therapeutic lasers (where the mechanism is not based oh heat):

Laser	Wavelength	Use
GaAs	904 nm (super pulsed)	Treatment of deep problems (back, shoulders, knees, head ache etc)
GaAlAs	780-808-890 nm (cont. or chopped)	Also deep problem, often a complement ot the GaAs-laser
InGaAlP	630-700 nm	Treatment of skin and mucose problems
HeNe	633 nm	Alternative to InGaAlP (see above)

Thermal lasers (for surgery or esthetic use):

Laser	Wavelength	Use
Ruby	694 nm	Hair removal (for Q-switch type: tattoo bleaching)
Nd:YAG	1064 nm	Coagulation of tumors, eye surgery (cataracts)
Ho:YAG	2130 nm	Crushing of kidney stones, surgery
Er:YAG	2940 nm	Dental drill, laser peeling of wrinkles and scars
KTP/532	532 nm	Coagulation of blood vessels, hemangioma.
Alexandrite	755 nm	Hair removal (for Q-switch type: tattoo bleaching)
CO2 laser	10600 nm	Surgery and laser peeling of wrinkles and scars
Argon	514 nm	Eye surgery (treatment of retinopathy)

There are many other types, but those mentioned above are the most common.
