Mechanics of Helium-Neon (He-Ne) and Carbon Dioxide (CO2) lasers.
A standout feature is Laud’s discussion of —the Achilles’ heel of practical nonlinear optics. Using clear diagrams of refractive index versus wavelength, he shows how birefringent crystals or quasi-phase-matching (e.g., periodically poled lithium niobate) can achieve efficient energy transfer over macroscopic distances.
Each section features carefully curated problems that test conceptual understanding and numerical problem-solving skills, making it excellent preparation for competitive graduate exams. 4. Real-World Applications Covered in the Text laser and nonlinear optics by bb.laud PDF
The second portion of the book transitions into how high-intensity laser light alters the optical properties of a material medium.
Laser and nonlinear optics is a branch of physics that deals with the study of the behavior of light in nonlinear media. Nonlinear optics is a field that has emerged in the 1960s, with the discovery of the laser. The intense electromagnetic field of the laser beam can interact with matter in ways that are not possible with traditional light sources. This interaction leads to a range of nonlinear optical phenomena, including second-harmonic generation, self-focusing, and soliton formation.
Laud details the essential architecture required to build a functioning laser:

The book has undergone several revisions to include recent technological advances.
"Lasers and Non-linear Optics" by B.B. Laud provides a comprehensive, pedagogical overview of laser physics and nonlinear phenomena, bridging quantum theoretical foundations with practical applications. The text covers essential topics including stimulated emission, various laser systems (gas, solid-state, semiconductor), and nonlinear interactions like harmonic generation and self-focusing.

If you are a student who cannot afford the physical copy, speak to your college librarian. Most institutions can broker a legal digital acquisition for you. In the meantime, use the previews and the structural guidance above to master the two most important fields of modern optics:
Nonlinear optics is defined by the study of how intense light interacts with matter such that the material's response is no longer proportional to the light's electric field. Laud’s text synthesizes research from various journals into a unified framework. Key topics include: Can’t copy the link right now
