Abstract

A laser system comprises a pump source, a Iasing medium and a spatial intensity control means. The pump source is operable to generate pumping radiation directed to the Iasing medium via the spatial intensity control means. The position of the Iasing medium is fixed with respect to the position of the pump source. The Iasing medium has a spatial extent to allow the pumping radiation to excite Iasing at different locations in the Iasing medium over time. The spatial intensity profile of the pumping radiation incident at the lasing medium is varied over time using the spatial intensity control means. The spatial intensity is controlled by time-varying reflection, refraction and/or interference of the pumping radiation.
