The technique produces light pulses with very high power - much higher than would
be produced by the same laser operating in a constant output (continuous wave) mode.
Compared to other techniques for pulse generation with lasers, Q-switching allows
lower pulse repetition rates, higher pulse energies, and longer pulse durations.
Thanks to these differences, Q-Switched lasers have become recognized largely as
the gold standard for most laser tattoo removal because they more effectively break
up the ink into particles which can then be eliminated by the patient’s own immune
A Q-switched laser (quality-switched laser) is a laser that emits short, high power
pulses; Q-switching, also known as giant pulse formation, allows a laser to produce
a pulsed beam of light.
