OPTICS PHOTONICS International 2026 Congress

WELCOME

We are pleased to announce the 15th International Conference on High Energy Density Laboratory Astrophysics (HEDLA), to be held April 20-24, 2026, at the Pacifico Yokohama in Yokohama, Japan. This conference will be co-located with the International Conference on High Energy Density Science (HEDS) as a part of the Optics and Photonics International Congress (OPIC).
HEDLA is a topical conference series that started in 1996 and has run approximately every other year since then. The goal is to use or develop laboratory experiments to understand high-energy-density phenomena in the universe.
HEDS covers the high-energy-density sciences with high-power lasers and their applications.
The deadline for registration is December 22. The registration will be done through the OPIC web page. Details will be announced soon.

SCOPE

High-power lasers and pulsed-power facilities enable the creation of extreme states of pressure and temperature well beyond those attainable under terrestrial conditions. Such high-energy-density states provide a powerful platform for exploring fundamental processes in astrophysical plasmas, which remain among the most compelling subjects in modern science. Laboratory astrophysics, in particular, offers a unique and complementary research methodology, advancing our understanding of astrophysical phenomena through controlled experiments in conjunction with astronomical observations and theoretical or simulation studies, while fostering collaboration across diverse scientific communities. Proposed Topics include, but are not limited to, the following areas of high-energy-density laboratory astrophysics:

• Fluid and Collisional Plasma Dynamics: jets, turbulence, dynamos, instabilities
• Collisionless Plasmas and Particle Acceleration: shocks, magnetic reconnection, kinetic processes
• Transport and Atomic/Radiative Processes: heat conduction, anomalous resistivity, diffusion, radiative transport, opacity, spectral line shapes, photoionization
• Dense Plasma Physics: equations of state, warm dense matter, planetary interiors
• New Frontiers in High-Energy-Density Science: quantum electrodynamics effects, pair plasmas, nuclear astrophysics, emerging experimental facilities, and advanced computing
