The ultra fast laser is a special type of laser that can produce pulses less than 100 picoseconds (10-12
seconds). In the specialized literature, "ultrashort" refers to the femtosecond (fs) to picosecond (ps) range. In optics, an ultra short pulse of light is an electromagnetic pulse whose time duration is on the order
of the femtosecond (10- 15second).
The term ultrafast lasers is often used for mode-locked lasers emitting ultrashort pulses. However, strictly speaking these lasers are not ultrafast, but only the involved phenomena. Therefore, the better term is actually ultrashort pulse lasers. Note that ultrashort pulses should not be called "ultrafast" – they
are not faster (don't have a higher velocity) than longer pulses.
