Abstract
A laser device and a method of pumping a laser gain medium (R) comprise directing pulses of laser light from a pump laser () to a series of separate locations (and) arranged longitudinally along the gain medium (R) in the direction of laser propagation. Each pulse of laser light generates a population inversion in an associated portion of the gain medium (R) just ahead of the laser photons. The pulses from the pump laser () are transmitted by a splitter () to the series of separate locations by optical delay lines (and) and each delay line is arranged to pump a different portion of the gain medium to cause a localised population inversion. The pulse transmission delays deliver a sequence of pulses to the portions of the gain medium (R) such that each portion will in turn contribute to amplification of a laser propagating within the gain medium (R).
