Description of Work: 

Objectives:

Coherent transient experiments, including optical free induction decay, photon echoes and optical nutation, facilitate an understanding of subtlest details of electronic structures in the solid state. The project aims to investigate the application of coherent transients in chemically interesting systems, such as coordination compounds, by laser-frequency switching of semiconductor (diode) lasers.

Description of Work:

  • Establish the facile induction of coherent transients by laser frequency switching of diode lasers by utilizing archetypal materials such as ruby, emerald and the like.
  • Transfer the technology to more challenging systems such as coordination compounds.
  • Studying the effects of external electric and magnetic fields on the coherent transients.
  • Gain a full theoretical understanding of the observed transients.
