    • A corrosion resistant fluid cooled acousto-optic AO device (300) includes an AO interaction medium (301) and a piezoelectric transducer (315) affixed to the AO medium (301). A cooling arrangement is thermally coupled to the AO medium and includes a first material, and at least one cooling conduit in thermal contact within the first material formed from a second different material having an inlet (in, coolant in) and an outlet (out, coolant out) coupled thereto. The conduit provides a channel having an inner surface for flowing a coolant fluid therethrough, wherein the conduit includes a continuous corrosion resistant material layer over its entire area of the inner surface. The first material provides a specific acoustic impedance closer to a specific acoustic impedance of the AO medium as compared to the corrosion resistant material, and a bulk thermal conductivity at 25 C of at least 75 W/m-K.
    • 耐腐蚀流体冷却声光AO装置(300)包括固定在AO介质(301)上的AO相互作用介质(301)和压电换能器(315)。 冷却装置热耦合到AO介质并且包括第一材料,以及由第二不同材料形成的第一材料内的热接触中的至少一个冷却导管,其具有入口(入口,冷却剂)和出口(出口) 冷却剂流出)。 导管提供具有用于使冷却剂流体流过其中的内表面的通道,其中导管在其内表面的整个区域上包括连续的耐腐蚀材料层。 与耐腐蚀材料相比,第一种材料提供比AO介质更接近特定声阻抗的特定声阻抗,并且在25℃下的体积热导率至少为75W / m-K。
