Diode laser

Diode Laser

A diode laser is also known as injection laser which is a semiconducting device producing coherent radiation, where all the waves are of the same frequency. Laser diodes are used in optical fiber systems, laser printers, remote control, etc. It basically uses a light beam with a narrow spectrum to target specific chromosomes in the skin, when used for the aesthetic purpose. In comparison to other laser treatments, the diode laser offers the deepest penetration level and superior melanin absorption. These characteristics of the diode laser make it most suitable for laser hair removal, since it enables the safest and most effective treatment for all skin and hair, in the body.

How does a Diode laser work?

A diode laser uses the principle of selective photothermolysis to target specific chromophores in the skin that is melanin or blood. The lasers damage the chromophores by selectively heating the target areas while leaving the surrounding tissues unharmed. When diode laser is used to treat unwanted hair in the body, the melanin in the hair follicles is targeted and damaged without disturbing the surrounding tissues. This damage to the melanin disturbs the growth and regeneration of the hair. The best part of a diode laser is that it is complemented with a cooling technology or other pain-reducing methods which not only improves the efficiency of the treatment but also ensures the patient's comfort.

Benefits of diode laser

  • A diode laser usually ranges less than one millimeter across and weighs a fraction of a gram making it a portable electronic equipment
  • The diode lasers require low currents (3-12 volts DC) and few mill amperes. So they can be operated using small battery power supply
  • This laser has low intensity so it cannot be used for burning holes in metal or bringing down satellites. But it can be used for aesthetic purposes producing the most efficient results
  • A laser diode produces a wide angle beam which can cover a greater surface area
