Laser surgery of skin conditions having cosmetic LASER CHARACTERISTICS implications has revealed the profound psychological
benefits which are unmatched by any other modality
of treatment either with or without a knife. An increasingly sophisticated understanding of the biophysics of laser- tissue interactions has lead to a more efficient utilization
of the present technology on the clinical side and at the same time is helping the physicists to add more and more highly selective laser systems in the armamentarium of aesthetic laser surgeons.
Laser light is monochromatic, bright, unidirectional and coherent.
Monochromaticity:The luminous waves emitted come out with the same wavelength and energy. A single wavelength or a narrow band of wavelengths emitted allows precise targeting within tissue, while sparing adjacent structures.
