Abstract

A short pulse, high power laser system provides oppor-tunities for producing and diagnosing various kinds of high speed phenomena such as the study of radiative and kinetic properties of laser-produced plasmas. We have developed a high power phosphate glass laser system for laser fusion research at Osaka University. This four beam system de-livers output energy of 2 kJ in 1 ns and output power of over 4 TW in 10 ps. The peak intensity at the focal point reaches ≈5x10¹⁷ W/cm². Characterization of the system performance based on simulation calculations and experimen-tal measurements are described.
