Research progress on temporal-spectral-spatial domain precision regulation technology for high-power laser drivers under operational conditions

High-power laser facilities serve as essential drivers for achieving extreme material states in laboratory settings, playing indispensable roles in high-energy-density physics, laboratory astrophysics, and laser-driven inertial confinement fusion (ICF) research. Following the historic milestone of the National Ignition Facility (NIF) achieving fusion gain exceeding 1, China’s ICF theoretical and experimental research has advanced new requirements for service-oriented operation of high-power laser facilities. This article presents recent progress by the Research Center of Laser Fusion (RCLF) from China Academy of Engineering Physics (CAEP) in addressing demands for precision beam conditioning and enhanced experimental flexibility.
