Green energy with diamond-based power electronics

Electricity generated from renewable energy sources often needs to be transported across long distances – for example from off-shore wind power plants to end users in the foothills of the Alps. The power electronic components currently used, however meet their limits when transferring high voltages and cause considerable energy losses. Fraunhofer IAF is therefore researching on new electronic components based on diamond: With its extraordinary physical properties, the material could soon help to establish smart-grid technologies, reducing energy losses and allowing for intelligent and flexible electronic networks.


Motivation for new paths in science: Award for Dr. Vera Gramich

Less Heat – More Power: Novel pumping concept for semiconductor disk lasers boosts efficiency

We demonstrate a diode laser pumped semiconductor disk laser (SDL) at 2 μm wavelength of increased efficiency. By employing a novel pumping concept at a wavelength of 1470 nm, we optimize the power conversion efficiency of the 2 μm SDL. This is exemplarily shown for an SDL with an output power of over 20 W in continuous wave operation. This sets a new benchmark regarding efficiency and output power for these SDLs.


REACH: safe handling of lll-V compound semiconductors

Power electronics of the future cannot be imagined without lll-V semiconductors: Smartphones, LEDs or lasers benefit from the special physical properties of these materials.
