Wigner
Laser and Spectroscopy Center

The mission of the Wigner Laser and Spectroscopy Center is to provide external partners with state-of-the-art femtosecond laser, ultrafast science and spectroscopy equipment in Budapest. With several infrastructural developments realized in our laboratories since 2012, we offer a unique combination of equipment for the science of light and its broad applications in physics, chemistry and biology.
