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.
