Spectral hole burning

Spectral Hole Burning (English spectral hole burning ) is a term from the physics of laser and one of the two forms of the hole burning.

When spectral hole burning the amplification of certain frequencies in the electromagnetic spectrum in the laser cavity is suppressed due to over saturation. The effect occurs in inhomogeneous line broadening, eg in Doppler broadening. The radiation interacts with the laser resonator of different atoms or molecules, i.e., the particles can be excited by unwanted frequencies. These atoms are then no longer for the actual laser process available. In the spectral representation ( frequency vs. population inversion or gain applied ) then result so-called Bennett holes ( according to William R. Bennett ).
