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 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.
其他摘要	在固态激光装置1中，用于使冷却剂循环通过固态激光介质3的主管11设置有热交换器14，从而防止激光介质3升高其温度。当冷却剂变为酸性或碱性时，控制器24控制流量调节阀23，以增加流入设有去离子过滤器22的旁通管21的冷却剂的流量，从而冷却剂的酸度或碱度可以被削弱了。这可以防止冷却剂劣化激光装置3的预定部分，因此可以提高固态激光装置1的耐久性。另外，由于与主管11的一部分并联连接的旁通管21是通过设置去离子过滤器22，可以抑制在主管11中循环的冷却剂的流量减少，并且可以防止激光介质3的冷却效率降低。
主权项	A solid-state laser apparatus adapted to cool a solid-state laser medium with a coolant, the apparatus comprising: a main pipe for circulating the coolant through the solid-state laser medium; cooling means, provided in the main pipe, for cooling the coolant; a bypass pipe connected in parallel to at least a part of the main pipe; neutralizing means, provided in the bypass pipe, for weakening an acidity or alkalinity of the coolant; flow regulating means, provided upstream of the neutralizing means in the bypass pipe, for regulating a flow rate of the coolant flowing into the bypass pipe; and control means for controlling the flow regulating means such as to increase the flow rate of the coolant flowing into the bypass pipe when the coolant is acidic or alkaline.
