Abstract
In a solid state laser assembly (12), arrays (60) of pumping laser diode bars (62), placed on opposed sides of a laser rod (36), are maintained at an optimal operating temperature by a pair of heat pipes (16) physically and thermally coupled at their respective evaporator sections (18) to both the diode bars and the laser rod. The laser assembly includes a pump cavity (34) configured as an I-beam having two pairs of terminal interfaces (58) respectively bounding a pair of elongated U-shaped channels (48). Heat from laser rod (36) is conducted through pump cavity (34) to the heat pipe evaporator sections (18). A mounting block (64) physically and thermally supports each of the diode array assemblies for spreading heat therefrom also to the evaporator sections.
