The Lab

Research in the de Vries Group involves a powerful combination of Laser Spectroscopy and Mass Spectrometry by employing laser induced desorption of molecules from surfaces, photo-ionization, multiphoton spectroscopy, femtosecond spectroscopy and mass spectrometry.

Molecular Beam Machine

This instrument combines high resolution gas phase laser spectroscopy and mass spectrometry. The instrumental methodology consists of : (1) laser desorption, (2) supersonic jet cooling, (3) post-ionization, and (4) time-of-flight mass spectrometry.

Microscope Laser Mass Spectrometer

Combines capabilities of Molecular Beam Machine with a high spatial-resolution stage and microscope, resulting in spatially resolved mass spectrometry on a micron level.

Femtosecond Experimental Setup

Using the spectra physics ultrafast oscillator and amplifier systems we can generate ~ 150fs laser pulses in the UV and IR for pump-probe spectroscopic measurements on molecules exhibiting fast excited state dynamics.

Laser Systems

The de Vries lab maintains a variety of laser systems, in addition to having access to the to the UCSB Optical Characterization Facilities.
