Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet)
Technology, Applications: Techniques used to target the pigment of the skin. It is used to deal with a variety of skin disorders. It is a simple technique to deal with tattoo elimination.
Below are the key elements:
Laser: Lasers are monochromatic. Gain medium determines the moving of wavelength with the help of photon emission. That means no chance of light beam spread. Lasers used for tattoo removal with class IV devices. Safety precautions should use by the patient before undergo with this treatment.
Gain Medium: It is in the form of solid, liquid or gas. Solid-state gain medium used to remove tattoos. 1064 nm wavelength used in the tattoo removal process.
Tattoo removal is Alexandrite (755 nm) and Ruby (694 nm) is a common gain medium. 1064 nm laser emission is passed through a KTP crystal (Potassium Titanyl Phosphate) to create 532 nm laser energy.
Finally the Q-switching mechanism will determines the function. It helps for removal of hair.
Q-Switching Mechanism: It produces short bursts of energy. It is capable of producing the power massively. This highest power helps to break the most stubborn inks. In addition to the tattoo removal, it is also helps to remove non-ablative skin resurfacing procedures and pigmented vascular lesions.
