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.

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.

A variety of laser types can generate picosecond pulses, with other performance parameters varying in wide ranges:

Compared with femtosecond lasers, picosecond laser sources are often more economical. In applications such as micromachining, they offer similar performance.
