Research in the Laser and Photonic Systems Group at the University of Rochester, Institute of Optics is guided by John Marciante, Associate Professor of Optics.
Our Photonic Laser Development Laboratory is located in the Robert B. Goergen Hall for Biomedical Engineering and Optics.
Our research centers around the development of advanced laser sources and photonics technology for use in laser machining, LIDAR, remote sensing, displays, and other airborne and spaceborne applications requiring high reliability and efficiency.
Spefic areas of research include:
- Large-mode area fibers
- High-efficiency, high-power fiber lasers and amplifiers
- High-power ultrafast fiber lasers
- Fiber lasers at exotic wavelengths
- Brightness improvement of high-power semiconductor lasers
- Power scaling of fiber and semiconductor lasers
Descriptions of our current projects can be accessed from the research tab.
