Stimulated Emission - Stimulated Emission Cross Section

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).

    —Ronald Reagan (b. 1911)

    “She remembered home as a place where there were always too many children, a cross man and work piling up around a sick woman.”
    —Willa Cather (1873–1947)
