  • Sound velocity is an intrinsic property of material, which is equal to the spread velocity of weak perturbation. Measurements of sound velocity are very important for the research of equation of state, phase transition and component of matter at extreme conditions. A continuous side-release method which can work to terapascal pressure was newly developed. In this paper, we described details of high precision targets fabrication of this method, including requirements, methodology and detection. Also, key factors which lead to fatal issues are analyzed for better signals and reliability. Experimental results on SGIII prototype laser facility are shown to validate the technology of targets fabrication.
