%X This paper present the experimental records of the light emitting from heating lumines-cence at the back surface of aluminium foil or stepped targets, obtained by an optical ultra-fast speed streak camera. The target was irradiated by a focused high power laser beam with 500 J output energy in 1.2 ns FWHM pulse. The results showed that the degree of fllatness of the laser driven shock wave was obviously improved due to application of the special com-Lined lens. In these experiments the shock wave velocity in the step of aluminium target was obtained to be 17.6 m/ns, correspounding to shock wave pressure of 4.4 Mbar.
