Q-switched Nd: YAG lasers are highly pigmented selective targeting the endogenous melanin. The Q-switched device acts as an extremely high-speed shutter. It allows the Nd: YAG rod to store a large amount of energy and permits a single, high-energy, high-speed pulse to exit the cavity. It deposits energy in pulses in the range of nanoseconds. The beam can be made uniform or fractionalized. A fractional handpiece reduces the time the laser beam touches the skin and minimizes the damage in normal cells with a quick recovery time, as the laser’s energy is deposited on the skin surface in an interval pattern with islands of unaffected skin. Heat-induced steam cavities in the melanosomes cause the scattering of visible light, resulting in an ash white color at the site of treatment.
To remove birthmarks, moles, hyperpigmentation, and tattoos
This laser was designed to target various types of pigment in the skin and it can achieve significant lightening of pigmented lesions and tattoos.
The Q-Switched ND YAG laser utilizes two energy frequencies; 1064 nanometers, to target deeper skin layers, and 532 nanometers, to address hyperpigmentation and more superficial layers.
When it comes to laser tattoo removal, the Q-Switched ND YAG laser targets ink pigment and breaks it up into smaller particles through powerful bursts of energy
