Technically every laser machine has different energy status, wavelength and parameters. For laser hair removal treatment there are many laser machines available in the market with different wavelengths. Some of them are RUBY LASER 694nm, MEDIOSTAR DIODE LASER 810nm, LIGHT SHEER 800nm, ALEXANDRITE 755nm, ND YAG LASER 1064nm, GENTLELASE 755nm and some IPL machines with 430nm to 640nm wavelength. ( IPL is not a laser but being used for hair removal). Every laser has a different energetic effect and as well as results.

Wavelengths under 600nm are strongly absorbed by hemoglobin and protein, and wavelengths above 900nm are strongly absorbed by the water in tissue. Skin is relatively transparent in the range of 600nm to 900nm. Melanin bearing structures are the most attractive target for laser energy. Energy absorption by melanin decreases with increasing wavelength. Diode laser (810nm) features a perfect wavelength and pulse width, theoretically offering an advantage to treat all types of patients, darker skinned patients also and especially for Indian skin.
