Ultrafast Optical Spectroscopy in Pulsed Fields

In the optics laboratory at the Pulsed Field Facility, we maintain and regularly use a variety of time-resolved and ultrafast capabilities.

Generally these studies are performed in our DC Superconducting Magnets (fields up to 17 T), and in temperatures down to 1.5K or 300mK using pumped helium-4 or helium-3.


  • Ultrafast (100fs) Ti:sapphire oscillator (frequency doubling available)
  • Visible & IR Optical Parametric Oscillator
  • Pulsed whitelight generation via photonic crystal fiber
  • Picosecond pulsed lasers (blue, red wavelengths from Picoquant)
  • Instrumentation for time-correlated single-photon counting
  • Multichannel-plate PMT and avalanche photodiodes for time-resolved PL
  • 300 mm & 500 mm spectrometers (Acton)
