A term applied to a pulsed
laser, meaning that the
laser emission lasts as long as the pumping process is sufficient to sustain
lasing conditions. Typical pulse durations are in the
-
range, depending on the pumping source. When the operation
mode of a pulsed
laser is not specified as
mode-locked, Q-switched, or anything else, it must be considered as free-running.
