Diode Lasers Review (Soprano, LightSheer etc.)
Wavelength 800 - 810nm near infrared wavelength
Diode systems deliver a longer wavelength than the Ruby (694 nm) and the Alexandrite (755 nm) systems. Penetrating deeper into the dermis inhibiting follicular growth areas without causing as much epidermal injury as the Ruby or the Alexandrite laser. Diode lasers are more adapted for darker skin colours than Ruby or Alexandrite.
Diode systems are amongst the newest available for hair removal applications. They are small, portable and easier to use than many other systems as they don't need a flash lamp to act as a pump. This is because the semi conductor diode is one of the most efficient light sources available.
Shave the treatment site to reduce the smell of burning hair and stopping long hairs from getting in the way of the skin/ follicles being treated. If you are tanned use a sunscreen for several weeks before treatment to reduce the chance of pigmentation issues.
A contact cooling device is always used with this laser type. Diode lasers will provide temporary hair loss on most fluence settings, however, higher fluences used by experienced operators increase the possibility of permanent hair removal. At the time of treatment only mild discomfort should be felt and this is diminished with anesthetics.

After the first treatment hair regrowth is mostly delayed by 2 to 5 months. Multiple treatments usually result in long term hair reduction so long as appropriate fluence settings are used.
