CPA laser exhibits stunning capabilities. It can generate the largest field, the largest pressure, the highest temperature and accelerating field, making it a universal source of high energy particle and radiation. Many applications are for the greatest benefit of science and society. For instance, high energy electrons, protons and neutrons in nuclear, high energy particle in physics and astrophysics; In cosmology the accelerating field is sufficient to simulate general relativistic effects. Finally, high energy protons and neutrons could undoubtedly find important applications in the transmutation of nuclear waste.
