#### 6. Device Description
The diode laser is a surgical device intended for use in dermatologic and general surgical procedure. It utilizes a semiconductor diode with invisible infrared radiation as a laser source (808 nm). The laser power is delivered to the treatment area via a laser handpiece. The emission laser is activated by a footswitch.
The diode laser emits 808nm wavelength laser which is absorbed by melanin and at the same time greatly reduce the absorption by water and haematoglobin. The laser beam penetrates through epidermis into dermis and absorbed by melanin in hair and hair follicle, producing laser photothermal effect, conducting the energy from hair section to hair toot, rising temperature of melanin and decomposing it, thus reaching effect of hair removal.
During treatment, the Sapphire in handpiece assures reliable and constant cooling result for skin surface with the maximum comfort and safety. When the laser system starts to release energy, skin cooling system works automatically. The cooling system reduces the temperature of treatment area and increase treatment comfort.
The proposed device includes power supply system, central control system, cooling system, laser deliver system and safety feature.
The cover material of the proposed device is ABS (Acrylonitrile Butadiene Styrene) plastic. The patient contact components in laser handpiece include supporting plate which is made of stainless steel and
