Abstract
One of the most remarkable advances in laser technology is the chirped pulse amplification (CPA) technique invented in mid-1980s, leading to a rapid development of a new class of compact ultraintense lasers, operating in a power range from terawatt to petawatt.  When such a laser beam is focused onto a target with a focal spot of a few micrometers in diameter, the laser intensity on the target surface is extremely high, approaching 1022W/cm2 presently.  Under such an ultraintense laser irradiation, target surface will be highly ionized, forming a relativistic plasma.  The new physics and applications under such extreme conditions are emerging rapidly during the past decades.  In this presentation I will concentrate on the applications of the ultraintense lasers in sciences, not including the exciting ultrafast phenomena such as the generation of attosecond pulses, the fast dynamics in chemistry, etc.  These applications will bring us into a new era of a sustainable development of our societies.  The main topics include:

  • Advanced approach to fusion - fast ignition
  • Advanced ultrahigh-gradient particle accelerators
  • Novel light sources from THz to x-ray regime (including the Compton scattered x-rays when coupled with other technologies, i.e., electron beams)
  • Potential sources of energetic particles
  • Laser nuclear science
  • Advanced diagnostics (i.e., imaging, backlighting, and radiography)
  • Laboratory of astrophysics
