Spectral distribution of a high pressure CO(2) laser: experiment and theory
Applied Optics
|May 11, 2010
Abstract:
The spectral characteristics of a 10-atm CO(2) laser have been studied. The gain minima reveal broadening and splitting tendencies of the line, correlated with a spatial deformation. These effects are quantitatively explained by a theoretical model which underlines the role of transverse modes higher than TEM(00) on the spectral distribution. We have developed analytical formulas which can be used for any type of homogeneously broadened lasers.

02:39Emission Spectra
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.
01:09UV–Vis Spectroscopy: Beer–Lambert Law
The Beer-Lambert law describes the relationship between absorbance and concentration, which combines the principles established by scientists Johann Heinrich Lambert and August Beer. Lambert's law states that when light passes through a medium, the loss in intensity is directly proportional to the original intensity and the path length of the light. Beer's law proposed that the transmittance of a solution remains constant if the product of concentration and path length is constant. The modern...
