There is disclosed an apparatus for generating a high pressure by underwater shock wave of the type that it is provided with a shock wave generation chamber (1) of which an inner surface is formed into a shape of a part of a pseudo-ellipsoid of rotation and which is to be filled with liquid and a shock wave generation source (3, 4, 5) for generating shock wave at a first focus (2) of the pseudo-ellipsoid so that a high pressure may be applied by the shock wave to an object set in position at a second focus (9) of the pseudo-ellipsoid of rotation. To avoid contamination and other damage of said object the shock wave generation source comprises a laser means (5), an optical fiber member (4) and a focusing lens (3) for focusing a laser beam on the foregoing focus position (2). |
