The full title of the book is Lasers and Non-Linear Optics , which perfectly captures its core mission. Before the advent of the laser, optics was a predominantly linear science—meaning the light entering a material produced an effect directly proportional to its input. The laser changed everything. Its incredibly high intensity unlocked a new world of "non-linear" effects, where materials began to interact with light in surprising ways, like changing its color or shape.
