What is the defining feature of a Q-switched laser?

The defining feature of a Q-switched laser is its ability to deliver high-energy pulses very quickly, which is particularly effective in procedures like tattoo removal. The Q-switching technique allows the laser to produce extremely short bursts of energy, often in nanoseconds or picoseconds. This rapid delivery of energy helps to break down the pigment particles in tattoo ink into smaller fragments, which can then be naturally eliminated by the body.

The quick pulse duration minimizes thermal damage to the surrounding skin, making it safer and more effective for pigment-based treatments. This is crucial for achieving successful outcomes, especially since traditional lasers may not deliver energy in such a concentrated manner over a brief time, which is key in minimizing side effects while maximizing efficacy in treatments targeting pigmentation.
