Description
** this session needs to be on Thursday
We discuss applications of a versatile, auto-locking laser system consisting of an external cavity diode laser and waveguide amplifier. The diode laser, which is capable of being vacuum-sealed, can be frequency stabilized with reference to atomic, molecular, and solid state spectra using a digital controller that relies either on a pattern-matching algorithm or on first or third derivative...
Nitrous oxide is of interest for atmospheric composition studies. Spectroscopic remote sensing studies rely on the availability of accurate sets of line parameters for molecular atmospheric constituents. In this study we have extended the set of line parameters for nitrous oxide obtained using the speed-dependent Voigt line profile with a weak line mixing component. We have used five room...
Single photon absorption and decay is the process where an atom emits or absorbs a single photon whose energy is equal to the energy difference between atomic energy levels. In two photon processes, an atom emits or absorbs two photons whose energies sum to the energy difference between atomic energy levels. The study of two photon processes has multiple applications in several fields of...
