Abstract
In this article, the structure and performance of the designed and constructed laser facility to perform basic research on the field of inertial confinement fusion and laser-plasma interaction have been studied. The laser facility has four laser beams and the optical amplifiers are based on the phosphate Nd:Glass solid-state active medium. The vacuum spatial filters have improved the beam quality and reduced the misalignment sensitivity of the optical structure. More than 30 Joules per beam have been achieved, and the total optical energy of the laser facility exceeds 120 J. The laser facility is upgraded to increase laser optical energy to 500 J. Temporal pulse-shaping of the laser master oscillator, the optical self-alignment systems, and equalization of the propagation time of laser beams from the laser source to the target position based on the heterodyne interferometer, are the main activities to make the implosion experiments of the pellets filled with the heavy isotopes of hydrogen for studying the inertial confinement fusion.
