Photonics and spectroscopy

Includes Laser Physics, Mediphotonics and Quantum Optics and the Photonics Laboratory.  Laser spectroscopic techniques have been pioneered at City College and are being used to study dynamical properties of a variety of physical and biological systems. Several laboratories cited in the research sections above make extensive use of laser-scattering and laser-based diagnostic techniques.

Beyond this, City College has a comprehensive research program in quantum optics and applied quantum phenomenology.
