Patent ID: 7542495

Claim:
A corrosion resistant fluid cooled acousto-optic (AO) device, comprising: an AO interaction medium and a piezoelectric transducer affixed to said AO medium, and a cooling arrangement thermally coupled to said AO medium, said cooling arrangement comprising a first material, and at least one cooling conduit thermally contacting said first material formed from a second different material having an inlet and an outlet coupled thereto, said conduit providing a channel having an inner surface for flowing a coolant fluid therethrough, wherein said conduit includes a continuous corrosion resistant material layer over its entire area of said inner surface, wherein said first material provides a specific acoustic impedance closer to a specific acoustic impedance of said AO medium as compared to said corrosion resistant material, and a bulk thermal conductivity at 25 C of at least 75 W/m·K.
