GaAlAs/td>

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/td>

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)
