A picosecond laser delivers laser pulses with pulse durations that can be measured in picoseconds (trillionths of a second).
These lasers can deliver a much higher amount energy to the skin in shorter, faster bursts than nanosecond(billionths of a second) lasers, creating the photomechanical effect that shatters the targeted ink or pigment into even smaller fragments which can then be more easily eliminated by the body.
The SmartPICO is capable of delivering picosecond pulses at a very high peak power (nearly 2GW) to deliver superior clinical results.
