Photoabsorption and ionization cross sections in a seeded CO(2) laser mixture
Applied Optics
|February 20, 2010
Abstract:
Photon absorption and photoionization spectra in a CO(2) laser mixture seeded with selected low ionization threshold additives are presented. Such data are used to determine total absorption and ionization cross sections for some gases and vapors of interest. The results identify tripropylamine as an interesting seedent material, as it exhibits a longer wavelength photoionization effect essentially independent of the primary host laser gases.

Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
Deactivation Processes: Jablonski Diagram
Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...
