High Pressure Hybrid Rotational femto-second/pico-second Anti-Stokes Raman Scattering Spectroscopy

Abstract:

Starting with the aims, I will describe my PhD research and the results obtained so far. Working on high pressure hybrid rotational femto-seconds/pico-second anti-Stokes Raman scattering (CARS) spectroscopy, I will first describe the experimental setup, focussing on sum-frequency generation (SFG) using second harmonic bandwidth compression (SHBC) and using a pulse shaper with a spatial light modulator (SLM) to create a chirp free laser pulse after a thick quartz window. I will then talk about the MATLAB model that I built to generate theoretical spectra and the fitting procedure used to fit the experimental results. Finally, I will show the fitting results and I will give an outlook over how the research will proceed in the future. 

Bio:

Torge Mecker is a 3rd year PhD student in IMT at the University of Edinburgh. He completed his undergraduate degree in Chemical Physics (MChemPhys) here at the University of Edinburgh (2011-2016). During his time as an undergraduate, he spent a year working as an analytical chemist at Cytec Industries in Stamford, CT, USA. Now, as one of Prof. Mark Linne’s PhD students, Torge works with coherent anti-Stokes Raman scattering (CARS) spectroscopy. His project involves modelling CARS spectra at high pressures. His research is in a collaboration with Dr. Christopher Kliewer’s group at the Sandia National Laboratories in Livermore, CA, where Torge spent a year to perform the experiments for his PhD research.
