Quantum cascade laser spectroscopy: non-linear optics and population transfer

Abstract:

This thesis is concerned with the non-linear effects observed in the absorption spectra obtained with swept continuous wave quantum cascade laser (cw-QCL) radiation. The slower chirp rate afforded by cw-QCLs, compared with pulsed systems, allows different aspects of the population transfer and polarisation induced in a molecular transition to be elucidated: namely, adiabatic rapid passage and coherent transient effects.

The thesis commences with a brief outline of the architectu...
