英文摘要	A cooling device suitable for cooling a laser diode bar constituting a surface illuminating device as a light source for exciting a laser medium of a solid-state laser oscillator of high power. The cooling device is capable of flowing coolant at sufficient flow rate by reducing the pressure loss in the flow passage of the coolant in the device, to realize a light source device of small thickness with high cooling capability and high reliability. The cooling device comprises a first plate member (29), one or more second plate member (30) and a third plate member (31) to be joined together to form a laminated body. The second plate member (30) has grooved paths formed on both surfaces thereof and having depths greater than a half of thickness of the plate member, and also opened paths for communicating grooved paths formed on the first plate member (29) and the third plate member (31). The pressure loss in the flow passage of coolant is reduced by increasing a sectional area of flow passage by the grooved paths and the opened path of the second plate member (30) without lowering mechanical strength of the device and without increasing a manufacturing cost of the device.
