A brief overview of Picosecond Laser:
Pico- (p) is a prefix used in metric system of measurement to denote the size which is one-trillionth of a meter. This size is a thousand times smaller than nano- which is a billionth of a meter.
PS: If you are interested in learning about the advances in Nanotechnology and its applications in the World of Medicine, please refer to my earlier Nanotechnology post.
Picosecond (ps) LASER (Light Amplification by Stimulated Emission of Radiation) refers to a Laser that emits optical pulses with duration between 1 ps and (usually) some tens of ps.

Latest role of Picosecond Laser technique in the World of Medicine has been in the production of synthetic scaffolds in the field of Regenerative Medicine which is a rapidly growing field which is already rapidly changing the medical world.
Please see my earlier post on 3-D organ printing where you can see Dr. Anthony Atala, a urologist, who is the head of Department of Regenerative Medicine at Wake Forest University in North Carolina, U.S.A. printing out a 3-D kidney using biomimetic synthetic scaffold and cultured human kidney cells using a 3-D organ printer.
The researchers at the Fraunhofer Institute for Laser Technology (ILT; Aachen, Germany) and other Fraunhofer Institutes developed a picosecond laser technique process for producing these biomimetic scaffolds utilizing Picosecond Laser. These scaffolds closely resemble endogenous tissue and assist in the study of 3-D cell growth. They combine organic substances with polymers and produce 3-D structures suitable for building artificial tissue.
