The Physics of Laser Radiation–Matter Interaction: Fundamentals, and Selected Applications in Metrology

Detailed Summary

The book begins with the foundational principles of laser physics, where I guide readers through the concepts of coherent radiation, stimulated emission, and essential quantum mechanics that underpin laser operation. These core principles serve as a springboard for understanding how lasers interact with matter on a microscopic scale.

In subsequent chapters, I delve into well-known mechanisms such as absorption, reflection, scattering, and nonlinear optical phenomena that occur when laser light interacts with various materials. Beyond theoretical descriptions, the discussion includes practical considerations, such as the roles of frequency, power, and material-specific properties.

A significant portion of the book is dedicated to real-world applications, with a particular emphasis on metrology, a critical field for scientific and industrial precision. Topics covered range from laser-based distance measurement techniques to advanced spectroscopic methods used for determining material properties and environmental diagnostics. The book also addresses state-of-the-art advances in femtosecond laser systems and their cutting-edge applications.

By weaving together these foundational and applied aspects, the book provides readers with a holistic understanding of the indispensable role lasers play in modern technology, research, and industry.
