Picosecond lasers are the next generation of lasers in the field of rejuvenation and multi-colour tattoo removal. There are vendors that use a technique called Pulse Slicing, which creates slower Q-switched nanosecond pulses that make it appear to be within the picosecond range.
This short, informative video shows this technique, as well as what the advantages of a real picosecond laser are, such as the PicoWay laser of Candela Medical.
