SPIE Visiting Lecture
3rd October, 2016
We are very happy to announce that our first SPIE visiting lecture will be held on 3rd of october, 2016. The lecture will be delivered by one of the eminent personality in the field of optics and photonics, Prof. Prasanta Kumar Datta, Department of Physics, IIT Kharagpur.
Prof. P. K. Datta, joined the Department of Physics, IIT Kharagpur in 2000 and developed a laboratory for ultrafast nonlinear optics with funding from various Government agencies in India and international Collaboration projects funded by JSPS, Japan, Ministry of Education, Italy and ICTP, Italy. Presently he is working on ultrafast science by developing femtosecond pump-probe, THz Spectroscopy, Z-scan and time-resolved MOKE facility in his laboratory. He received his undergraduate and post graduate degree from Calcutta University and Ph.D. from Burdwan University.
Before joining IIT Kharagpur, Prof. Datta worked in various scientific positions at Centre for Advanced Technology (DAE), Indore, DRDO, Pune and Physical Research Laboratory (ISRO), Ahmedabad. He did his postdoctoral research work on different aspects of nonlinear optics at Pavia University, Italy and Strathclyde University Scotland, Heriot-Watt University, Scotland, Scuola SuperioreSant’Anna, Pisa, Italy, University of Michigan, USA, INRS, Montreal, Canada and Universita Cattolica, Brescia, Italy. He has 62 publications in internationally refereed journals and have produced 8 Ph.Ds so far.

Abstract of Talk
Introducing the different methods of THz generation and their pros and cons, the optical rectification applied in a ZnTe crystal with a femtosecond optical pulse at 800nm for the generation of efficient and wide band-width THz radiation will be described. The effect of pulse shape and its chirping on the efficiency and bandwidth of the generated THz radiation will be presented. The generated THz radiation is used to obtain time domain THz absorption spectroscopy in doped GaSe to identify the combinational phonon modes.
