Abstract
A pumping module for use in a solid state laser comprises an annular array of laser diode segments (10) forming a passage (24), each segment (10) comprising an extended body supporting a laser diode array (17) that extends along the longitudinal axis of the segment (10) for directing light into the passage (24) from an inner face (12) of the annular array, wherein adjacent side faces of any two segments (10) in the annular array are in sealing engagement. The inner faces (12) of the array of segments (10) form a continuous surface so that coolant can flow between a laser rod and the segments (10) to reduce localized heating.

A pumping module for use in a solid state laser, comprising 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 surface of the annular array, the laser diode array being located between a first portion of the segment comprising an anode and a second portion of the segment comprising a cathode, wherein adjacent side faces of any two segments in the annular array are in sealing engagement, so that the anode of one segment abuts the cathode of an adjoining segment.
