Stimulated Raman transition (source code)

= Stimulated Raman transition
{title2=$\Delta E=\hbar(\omega_1-\omega_2),\quad\Delta\mathbf p=\hbar(\mathbf k_1-\mathbf k_2)$}

Coherent <absorption> from one applied beam and <stimulated emission> into another, transferring an atom between two long-lived states. The <energy> transfer uses the <frequency> difference and the <momentum> transfer the <wavevector> difference. It is distinct from an absorption-absorption process.
