In this post, we will see the book Lasers and Their Prospects by N. Sobolev.
About the book
This book explores various aspects of lasers from their basic principles of its operation to applications in diverse fields. The book starts with a discussion on the nature of light and moves on the idea of the atom as a quantum system. In the next chapter, various properties of lasers and the basic idea behind the laser generation like active materials are discussed. the fourth chapter discusses various aspects of applications of lasers in diverse fields such as communications, computers, materials processing, range finding, medicine etc. In the next chapter aspects of laser usage in scientific studies is discussed. The final chapter discusses the future prospects of laser usage.
The book was translated from the Russian by V. Purto and was published by Mir in 1974.
