Germany's DioHELIOS Project Advances Diode Lasers for Fusion Power Plants
The DioHELIOS project in Germany aims to enhance diode laser technology for future fusion power plants, targeting pump sources that can achieve costs below 2 cents per watt. Funded by BMFTR, the initiative seeks to improve efficiency and scalability of high-power laser diodes necessary for inertial fusion energy applications.

The DioHELIOS project, which is part of Germany's 'Fusion 2040' initiative, is focused on developing high-power diode laser modules essential for future fusion power plants. The project aims to significantly reduce diode production costs from approximately €1 per watt to below 2 cents per watt through innovative semiconductor designs and manufacturing techniques.
The consortium, comprising ams-OSRAM, FBH, and several industrial partners, is addressing the inefficiencies associated with current flash lamp technology and exploring methods to enhance output power and operational efficiency. With a total funding of €17.3 million from BMFTR, the project is positioned to advance the commercial viability of laser-based fusion energy, which holds the potential for carbon-neutral energy production.
