Abstract
A light source device for pumping a solid-state laser medium of a laser generator, which is compact and capable of economically using LD bars constituting the LD stack with easy maintenance. The light source device is constituted by a plurality of LD modules. Each LD module comprises a plurality of cooling devices on which LD bars are respectively mounted and connection plates on both sides thereof. The LD bars are stacked such that longitudinal directions thereof extend perpendicular to a stacking direction thereof. A desired number of LD modules are mechanically connected with each other using the connection plates to form the LD stack. A sealing member is intervened between confronting connection plates of adjacent LD modules, so that flow passages of coolant formed in the respective LD modules are continuously connected. The connection plates have functions of fixedly supporting the cooling devices of each LD module and electrically connecting the adjacent LD modules.
