Topic: Supercontinum Generation in Potassium Dihydrogen Phosphate Crystal Using a fs Laser.

Speaker: Professor Narayana Rao, School of Physics University of Hyderabad, India

Date & Time: Wednesday, November 9, 2005, 2:30 PM

Place: Room 137 VMC (Chambers Hall)



A new method of achieving broadband femtosecond white light in Potassium Dihydrogen Phosphate (KDP) crystal will be presented. Enhancement in the bandwidth of white light towards the shorter wavelength regime has been achieved by employing supercontinum generation and sum frequency generation in tandem. We will also look at a novel way of achieving broad and flat spectrum by using a tandem arrangement of differently oriented crystal slices.



Professor Narayana Rao obtained his Ph.D. from IIT Kanpur in fluorescence spectroscopy in 1979. He was a research associate at IIT Dehli for one year working on the Raman Spectroscopy of semiconductors. For the next ten years he worked at State University of New York at Buffalo, UMASS and MIT respectively. He then joined University of Hyderabad in 1990. His areas of interest include Nonlinear Optics and Spectroscopy (SHG, FWM, Z-Scan, Incoherent Spectroscopy) as well as Singular Optics and Ultrafast Phenomena.

Refreshments will be served at 2:15 PM
