A picosecond laser is a laser which emits optical pulses with a duration between 1 ps and (usually) some tens of picoseconds. It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers.
The picosecond laser is a revolutionary laser technology due to its much shortened pulse duration of just 1012 seconds. 1. Laser treatments in skin of color may result in unwanted side effects, such as postinflammatory hypo- or hyperpigmentation or even scarring.
Picosecond Laser is a technology that helps treat freckles, blemishes and wrinkles, as well as stimulates the production of collagen to make the skin smooth and wrinkle-free. Picosecond Laser is also used to remove tattoos
Sometimes, other laser-based sources for picosecond pulses-for example synchronously pumped OPOs-are also called picosecond lasers, even if they are strictly speaking no lasers.
