Thesis Abstract

Towards the construction of an automated two dimensional optical spectrometer using femtosecond pulse shaper

The study of quantum optics and quantum electronics experimentally has gained momentum after the invention of ultrafast lasers. The very short duration pulses which are of order 10-15sec enable study of such phenomena which occur in similar timescales in a time resolved manner. These experiments can also reveal couplings between vibrational modes and chemical dynamics. A two-dimensional spectrometer is a device to investigate the above mentioned phenomena. This work is an e ort to design and implement a two dimensional spectrometer capable of investigating the above phenomena in depth. The thesis starts with the implementation of pulse characterization techniques which are instrumental in measuring the parameters of ultrashort pulses. Two most convenient and relevant techniques, STRUT and FTSI, have been discussed. Then the construction and calibration of the pulse shaper has been explained in detail and at last the pulses which are instrumental in two dimensional spectroscopy have been generated and characterized. The programs necessary to perform full characterization of the pulse shaper as well as to acquire the spectroscopy data in real time have been implemented and tested.
