Abstract
A pumping module for use in a solid state laser comprises an annular array of laser diode segments ( ) forming a passage ( ), each segment ( ) comprising an extended body supporting a laser diode array ( ) that extends along the longitudinal axis of the segment ( ) for directing light into the passage ( ) from an inner face ( ) of the annular array, wherein adjacent side faces of any two segments ( ) in the annular array are in sealing engagement. The inner faces ( ) of the array of segments ( ) form a continuous surface so that coolant can flow between a laser rod and the segments ( ) to reduce localized heating.
