B.B. Laud’s Lasers and Non-Linear Optics serves as a foundational text bridging quantum theory with practical applications, often highlighting concepts like population inversion and nonlinear susceptibility. The material covers Einstein coefficients, maser systems, and detailed laser types, making it a critical resource for graduate-level physics, particularly regarding line broadening and phase matching.

The second half transitions to nonlinear optics—the study of how intense light modifies the optical properties of a medium. Laud begins by revisiting the polarization response of a material: at low intensities, polarization (\mathbfP) is linear in the electric field (\mathbfE) ((\mathbfP = \epsilon_0 \chi^(1) \mathbfE)). With laser intensities ((>10^6 , \textW/cm^2)), higher-order terms become significant: Laud begins by revisiting the polarization response of
