The High Average Power Laser Program
is a coordinated, focussed multi-lab effort to develop the science and
technology for Laser Inertial Fusion Energy (Laser IFE). Researchers
at UC San Diego support this national program in the areas of
optics development and testing,
chamber armor studies,
chamber gasdynamics and clearing,
chamber design integration,
and target engagement and survival.
More information on the national program can be found here.
Below we describe research performed at UC San Diego in support of the HAPL program.
- Optics development and testing
- Researchers at UC San Diego are responsible for the development
and testing of final optics for laser IFE. The leading candidate
for a final optic is a "grazing incidence metal mirror", or GIMM.
We work with industrial partners to develop fabrication techniques,
and we perform high-cycle exposures using short-pulse lasers in the UCSD
Laser Plasma and Laser Matter
- Chamber armor studies
- Chamber gasdynamics and clearing
- Chamber design integration
- Target engagement and survival
- In collaboration with the Inertial Fusion Group at
we are developing systems for tracking direct-drive inertial fusion targets
and steering multiple laser beams onto the target. Other activities include
electrostatic target steering and modeling studies of the thermal and
mechanical response of cryogenic targets in flight.
- Our experimental research is performed in the
Laser Plasma and Laser Matter Interactions Laboratory.
Light sources include Joule-class excimer and solid state
lasers. Target engagement research is also carried out at
the General Atomics IFE Target Laboratory.
