Lasers (Light Amplification by Stimulated Emission of Radiation) generate a coherent beam and emits one specific beam of wavelength. The lasers are specifically directed towards tissue of different types so as to produce a strong heat. This strong heat works by destroying the tissues without disturbing the surrounding region. The intensity and wavelength of lasers depend on the different treatments. Laser technology is extensively used in the areas of dermatology, neurosurgery, ophthalmology, cosmetic, podiatry, in specific cancer treatments, urology and dentistry.
