Q switching is a technique for obtaining energetic short (but not ultrashort) light pulses from a laser by modulating the intracavity losses and thus the Q factor of the laser resonator. The technique is mainly applied for the generation of nanosecond pulses of high energy and peak power with solid-state bulk lasers.
The Q-Switched Nd:YAG laser works by targeting specific pigment in the skin, which TARGETS the damaged skin cells in the treatment area. 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.
How many sessions does Q-switch laser require? Q-switched laser requires between 10 and 15 sessions. The tattoo should be completely removed in 1 to 3 sessions.
The Q-Switched laser is a versatile laser that offers different wavelengths to target a variety of skin conditions including sun spots, age spots, freckles, pigmentation and some birthmarks. An added bonus of this laser is its rejuvenation effect on the skin. The Q-switched laser has been around for many years.
