Light source device for pumping solid-state laser medium

摘要

A light source device for pumping a solid-state laser medium of a laser generator, which is compact and capably of economically using LD bars (1) constituting the LD stack (100) with easy maintenance. The light source device is constituted by a plurality of LD modules (5). Each LD module (5) comprises a plurality of cooling devices (2) on which LD bars (1) are respectively mounted and connection plates (3) on both sides thereof. The LD bars (1) are stacked such that longitudinal directions thereof extend perpendicular to a stacking direction thereof. A desired number of LD modules (5) are mechanically connected with each other using the connection plates (3) to form the LD stack (100). A sealing member (4) is intervened between confronting connection plates (3) of adjacent LD modules (5), so that flow passages of coolant formed in the respective LD modules (5) are continuously connected. The connection plates (3) have functions of fixedly supporting the cooling devices (2) of each LD module (5) and electrically connecting the adjacent LD modules (5). <IMAGE>
