Dr. John Fourkas

The Fourkas laboratory features state-of-the-art facilities for ultrafast spectroscopy, nonlinear optical microscopy, and materials synthesis and characterization. The current facilities include:

Ultrafast spectroscopy laboratory. Our ultrafast lab features clean-room-quality air with high temperature and humidity stability. The lab houses our optical Kerr effect spectrometers and micropscope, which are based around a KMLabs Ti:Sapphire oscillator. This lab is also home to a kHz Ti:Sapphire amplifier system with an optical parameter amplifier and difference-frequency generation system; we use this system in collaboration with Rob Walker’s group for vibrational sum frequency generation spectroscopy of liquid/solid interfaces.

Microscopy/fabrication laboratory. This laboratory, which is also climate-controlled, hosts three advanced microscopes and three different Ti:sapphire laser systems. One microscope is dedicated to two-photon imaging and features single-molecule sensitivity. The other two microscopes are used for multiphoton fabrication. Two of the lasers are broadly-tunable Coherent Mira 900s that are can be locked to within 200 fs with SynchroLock hardware. The other laser is a KMLabs oscillator that generates 20 fs pulses. Each laser can be used with any of the microscopes. This lab also features pulse-shaping and beam-shaping setups that use satial light modulators.


To view a 360 degree panorama of the Clark School of Engineering area as well as some other interesting places on campus, Click on the thumbnails images to open the QuickTime VR movies.
Then, drag your mouse to pan left or right, or click on hotspots to enter another room. You can also zoom in an out with the +/- buttons.

The "virtual tour" movies have "hot spots" that link to other areas or rooms. They are actually multiple movies combined into one, so the file size is rather large. It is best to view these with a high speed connection like T1, cable or DSL.

The Quicktime plug-in is no longer supported.

If you would like to see where these places are on a campus map and connect to the VR tours from there, see the
