A side pumped laser 5 comprises an elongated gain medium 10 provided between an output coupler 20 and a counter reflector 15. A pump source 65 is configured to provide radiation to the gain medium along a side 40 or long axis of the gain medium., wherein the laser 5 is configured such that radiation from the pump source 65 is directly incident on the gain medium 10; and the pump source is provided proximate, adjacent or in contact with the gain medium, The laser material and compositions, geometries and dimensions are designed to permit the use of construction techniques commonplace in the production of equipment designed for optical telecoms systems to facilitate low cost high volume and miniaturization which may produce sensors, lasers designators or a range finder. |
