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.
