What gives the Q-switched laser its ability to break down pigment effectively?

The ability of a Q-switched laser to effectively break down pigment is primarily due to its high peak power and short pulse duration. This type of laser produces extremely short bursts of energy, which can reach intensities sufficient to cause a rapid thermal expansion of the targeted pigments, such as melanin. The fast delivery of energy in these brief pulses minimizes damage to the surrounding tissues, making the procedure safer and more effective for pigment removal.

The targeted approach of high peak power allows for effective photomechanical effects as the laser energy is absorbed more readily by the pigment than by the surrounding skin. This selective targeting is crucial in cosmetic procedures, particularly for tattoo removal and treating pigmented lesions, as it leads to the fragmentation of the pigment into smaller particles, which can then be more easily removed by the body’s immune system.

Hence, this engineering of the Q-switched laser enables it to achieve optimal results in pigment breakdown while minimizing collateral damage.
