Laser‐driven shock experiments have been used to study the Equation‐of‐State (EOS) properties of liquid deuterium in the pressure range of 100‐600 Gpa. Reflected shocks are utilized to increase the shock pressure and to enhance the sensitivity to differences in compressibility. The results of these experiments differ substantially from the predictions of the Sesame EOS. EOS models showing large dissociation effects and having a greater compressibility (up to factor of 2) agree with the data.
