B.B. Laud’s Laser and Nonlinear Optics remains a valuable pedagogical resource precisely because it is not exhaustive. It distills the core ideas of two major subfields into a coherent, readable narrative. While contemporary researchers will need supplementary materials for cutting-edge topics, no other book of comparable length so effectively demystifies the journey from Einstein’s stimulated emission to the colorful, frequency-converted beams that define modern photonics. For anyone seeking a solid, mathematically gentle foundation in how lasers work and how intense light bends the rules of ordinary optics, Laud’s text is an enduring guide.

Laud dedicates significant space to the concept of ( \Delta k = k_1 + k_2 - k_3 ). Without phase matching, the efficiency of SHG is near zero. He uses vector diagrams and clear algebra to show how angle tuning in uniaxial crystals satisfies this condition.
The first half of Laud’s book systematically introduces the principles of laser action. Starting with the Einstein coefficients—absorption, spontaneous emission, and stimulated emission—Laud establishes the quantum-mechanical basis for light amplification. He then moves through essential topics: Would you like a chapter-by-chapter summary or help
Laud’s treatment is notably practical: he explains why different lasers suit different applications—for instance, why CO(_2) lasers excel at cutting metals, while He-Ne lasers are ideal for alignment and interferometry. The mathematics remains at the level of ordinary differential equations and basic quantum mechanics, making the text accessible to advanced undergraduates.
These techniques for generating high-intensity pulses (nanosecond vs. picosecond/femtosecond) are explained with timing diagrams and rate equations, making them digestible for undergraduate levels.
