Surface Plasmon Resonance and Localized Surface Plasmon Resonance Spectroscopy

     Resonant Rayleigh Scattering Spectroscopy

 

Some Images of our Specialized Equipment

Our setup for nonlinear spectroscopies such as CARS and stimulated Raman. It has two Ti:Sapphire oscillators which pulse in phase with eachother. Supercontiuum white light generation is also available on this optical table.

 

 

Our very own Shimadzu Axima-CFR MALDI-TOF mass spectrometer. This is used for studies on tunable laser desorption ionization.

A view of our fully tunable ultrafast laser system. It is composed of a Ti:Sapphire oscillator which pumps a Mira-OPO or a set of 2nd and 3rd harmonic generating crystals. This system is continuously tunable from ~350 nm to over 1 micron. Detection on this table is accomplished by a single spectrograph or a subtractive triple, ensuring tunable detection.

This image shows both the sample preperation chamber and cryogenic UHV-STM chamber. The tip-sample junction has optical access and is integrated into our tunable system depicted above.

 

 

 

The Molecular Imaging  PicoPlus SPM II allows both AFM and STM imaging of substrates.  This AFM/ STM machine can be integrated with our inverted microscope on the optical table.

 

To the left is our new e-beam vacuum deposition chamber.  We now have the ability to deposit up to 4 different materials without breaking vacuum.  Also thermal annealing and thermally heated depositions can be completed under vacuum.  Pump down time has been greatly reduced relative to our older deposition chamber.
