摘要： A solid-state laser apparatus 1 bounces laser light L2 between an end mirror 3 and an output mirror 4 via a slab-type solid-state laser medium 2 excited by excitation light L1 to thereby amplify and output the laser light L2. The solid-state laser medium 2 includes incident/exit end faces 2a, 2b on and from which the laser light L2 is made incident and exits, and reflecting end faces 2c, 2d which reflect the laser light L2 so that the incident laser light L2 propagates in a zigzag manner. The incident/exit end face 2a is made incident with the excitation light L1 so that the excitation light L1 propagates along substantially the same propagation path as that of the laser light L2 within the solid-state laser medium 2. Accordingly, a solid-state laser apparatus which can improve the coupling efficiency between the excitation light and the laser light is realized.

摘要： In the solid-state laser apparatus 1, a main pipe 11 for circulating a coolant through a solid-state laser medium 3 is provided with a heat exchanger 14, whereby the laser medium 3 is prevented from raising its temperature. When the coolant becomes acidic or alkaline, a controller 24 controls a flow regulating valve 23, so as to increase the flow rate of the coolant flowing into a bypass pipe 21 provided with a deionizing filter 22, whereby the acidity or alkalinity of the coolant can be weakened. This can prevent the coolant from deteriorating a predetermined part of the laser apparatus 3, and thus can improve the durability of the solid-state laser apparatus 1. Also, since the bypass pipe 21 connected in parallel to a part of the main pipe 11 is provided with the deionizing filter 22, the flow rate of the coolant circulating through the main pipe 11 can be restrained from decreasing, and the cooling efficiency of the laser medium 3 can be prevented from lowering.
