+its Light gets Amplified by [Stimulated Emission](/know/concept/einstein-coefficients/) of Radiation (LASER).
+After that, $$D_0$$ can be increased even further until some other $$k_n$$ become real,

 Below threshold (i.e. before any mode is lasing), the problem is linear in $$\Psi_n$$,
 but above threshold it is nonlinear via $$h(\vb{x})$$.
