ABSTRACT:
A device for producing laser radiation, the device comprising: an elongate sample of a quasi-three-level laser material; a source of pumping radiation; and a concentrator configured such that at least some of the pumping radiation emitted by the source of pumping radiation is concentrated by the concentrator and subsequently enters the sample through a side surface thereof.
