Stimulated Emission Cross Section
The stimulated emission cross section (in square meters) is
where
- A21 is the Einstein A coefficient (in radians per second),
- λ is the wavelength (in meters),
- n is the refractive index of the medium (dimensionless), and
- g(ν) is the spectral line shape function (in seconds).

Famous quotes containing the words emission, cross and/or section:
“Approximately 80% of our air pollution stems from hydrocarbons released by vegetation, so let’s not go overboard in setting and enforcing tough emission standards from man-made sources.”
