Hamamatsu Photonics has succeeded in producing laser pulses with energy of 100 joules (J) at a high repetition rate of 10 hertz (Hz). This was achieved by increasing the cooling capacity for the laser medium (*1) of the pulsed laser system and by optimizing the output of the laser diode (LD) module for pumping (*2).
To make laser fusion practical, the fusion fuel needs to be efficiently irradiated with a pulsed laser that produces as much as 1 megajoule (MJ) at a high repetition rate of 10 Hz. We believe that establishing this technology is an important milestone where the results from this study will help us move toward this goal.
We will present the results of this study at a symposium and general lecture at the "43rd Annual Meeting of the Laser Society of Japan" to be held at WINC AICHI (Nakamura-ku, Nagoya, Japan) from the 18th to the 20th January 2023.
*1: Laser medium is a material that stores energy from an outside source and amplifies the laser passing through it by imparting energy to the laser.
*2. Pumping is the process in which electrons in an atom or molecule are raised to a higher energy level due to light absorption.
