Wigner Laser and Spectroscopy Centre

Description of the RI

The mission of the Wigner Laser and Spectroscopy Centre 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.

Accessible instruments:

  • 5 fs / 2.5 nJ / 80 MHz Ti:sapphire oscillator with carrier-envelope phase stabilization (Venteon GmbH)
  • 35 fs / 7 mJ / 1 kHz regenerative Ti:sapphire amplifier & OPA (350 nm - 12000 nm, Newport-Spectra Physics)
  • 35 fs / 0.4 mJ / 10 kHz / 35 fs regenerative Ti:sapphire amplifier & OPA (350 nm - 4000 nm, Coherent Inc.)
  • 260 nJ / 3.6 MHz / 60 fs long-cavity Ti:sapphire oscillator (home-built)
  • time-of-flight electron spectrometers (Kaesdorf GmbH)
  • hemispheric electron spectrometer (Specs GmbH)
  • retarding field electron spectrometer (home-built)
  • ultrabroadband pulse diagnostics (FROGs and autocorrelators down to 5 fs pulses)
  • Micro-Raman spectrometer with mapping resolution 100 nm, 325/532/633/785 nm excitation (Renishaw in Via)
  • Femtosecond scanning stimulated Raman microscope (with Coherent Chameleon laser tunable between 750 and 1100 nm, 500 nm resolution)
  • Fluorimeter with double monochromator with 250-500 nm excitation, 290-800 nm emission (Jobin Yvon Flurolog FL322)


Activities and Services

Interaction of femtosecond laser pulse with different media enable several physics, chemistry and materials science research lines, including photoinduced chemical reactions, nanoparticle production and optical circuitry, to name a few. In addition, the micro-Raman spectrometer and the scanning stimulated Raman microscope can be used to determine composition, bonding configuration and other properties of liquid and solid (including biological) samples with sub-micrometer resolution and mapping.

User services include laser beam delivery to a user-defined target, operation of lasers, auxiliary infrastructure and spectroscopic measurements on samples delivered by external partners and if necessary, SEM imaging services.
