Second-order Nonlinear Optical Characterization Techniques : An Introduction

Designed for nonspecialists, this multidisciplinary book provides an overview of second-order nonlinear optical characterization techniques, such as second-harmonic generation and sum-frequency generation, which can be easily implemented in any lab. Avoiding extensive mathematical details, the authors present an elementary description of nonlinear optics and include several practical examples that show how to use nonlinear optics as a versatile characterization tool. They also describe how to implement nonlinear optical techniques for specific purposes, from the determination of surface symmetry and molecular orientation to biological imaging.

Although chemists, biochemists, biologists, and material scientists are often interested in using nonlinear optical techniques for characterizing their samples, they seldom have the necessary background to exploit these methods. Designed for nonspecialists, Second-Order Nonlinear Optical Characterization Techniques: An Introduction focuses on the potential of second-order nonlinear optics as a powerful characterization tool. Avoiding extensive mathematical details, this multidisciplinary book does not require a background in advanced mathematics or physics.

After introducing linear optics from the perspective of polarizability and linear susceptibility, the authors cover incoherent second-harmonic generation. They then deal with the study of surfaces and interfaces, exploiting the intrinsic surface sensitivity of second-harmonic generation and sum-frequency generation. The final chapter discusses second-order imaging techniques, including confocal microscopy and two-photon excited fluorescence microscopy.

Accessible to a wide range of scientists, this concise book stresses the reliability of nonlinear optical processes for probing surfaces and interfaces. Drawing on the insight offered in the text, scientists from many disciplines can now clearly understand and use second-order nonlinear optical methods.
