| The equation of state (EOS) is of great importance in Inertial Confinement Fusion (ICF), planetary physics, plasma physics, atomic bomb simulation, and material sciences. Laser generated Shockwave is so far the only way to access ultrahigh pressure regime as high as over 2 tera-pascals in laboratory. This paper presents the attempt of applying a long-pulse, low intensity KrF laser, Heaven-I, which is established in China Institute of Atomic Energy (CIAE), to testify the feasibility of EOS measurements in the High Power Excimer Laser Laboratory (HPELL).The work is intended to utilize the superior homogeneity of KrF laser beams to generate a uniform shockwave, directly or indirectly. Due to its wide bandwidth, KrF laser beam is ready to be homogenized by a method called Induced Spatial Incoherence (ISI) to generate uniform illumination on target, which is critical to EOS measurements. A long pulse is also preferred to get a 'cold' acceleration of flyer in impact experiments.In chapter 1, a brief review of recent EOS related work done on KrF lasers in the world is given. The experimental conditions available in HPELL are summarized, and the further necessities are analyzed.In chapter 2, the basic theory of the principle Hugoniot and the methods of fluid velocity measurement are briefly summarized.In chapter 3, an 1-D hydrodynamic code-HYADES is utilized to simulate shocks in direct laser illumination or flyer impact.Chapter 4, a large part of this paper, is devoted to describe the experimental setup, the laser beam reshaping, the beam diagnostics, and the improvements of a streak camera. This is also an important part of my work for it is to establish a stable experimental platform for the further research.Chapter 5, short but is the core of this paper. The flatter impact shockgenerated by a homogenized beam by ISI with strict image relay, and a round-shaped impact shock generated by ISI without strict image relay, is compared. It reveals the importance of ISI with strict image relay in planar shock generation. By applying the simulation to the measured flight time, a flyer velocity of 8 km/s is deduced in the experiment, which implies over 1 Mbar pressure in balanced impact.In appendixes , the validity of applying HYADES simulation to our experiments is analyzed.Some by-products of this work can be used as routine tools in the UV laser laboratory. Commercial video CCD cameras are used to image UV laser and soft x rays, window glass as a fluorescer is used to indirectly measure the UV laser beam profile with high energy density, and a special glass which permits UV light to pass through while absorbs the visible, is introduced into the UV beam profiling in strong visible stray light environment.In conclusion, a laser target shooting setup utilizing one single laser beam homogenized by ISI with image relay based on the KrF laser 'Heaven I' , laser beam diagnostics and shock-emission detection with streak camera have been established. Planar shock wave has been generated by flyer impact using ISI laser beam with strict image relay, above 1Mbar pressure is produced. Pressure enhancement by flyer impact will be the main work of HPELL to access Mbar or even higher regime. But before that, a great deal of work on planar shock generation which is critical to EOS measurements is on hand.
