Understanding Lasers: An Entry-Level Guide

College-level libraries strong in science and technology titles will appreciate this easy introductory guide to laser technology, which moves from the foundations of how lasers work and how they are used to discussions of specific advanced laser types, applications, and the science involved. Add drawings, tables, and multiple-choice quizzes and you also have a study guide suitable for college-level classroom assignments.

If you are a hobbyist, this is all you need to get started. A great book that leans towards the practical aspects, laser applications and avoids use of excessive math. The end of each chapter contains a summary and a small quiz that drives home the points to give you confidence. For example, you will be able to answer questions such as 'What is the length of a Q switched pulse from a 10cm long Neodymium-glass laser with 90% reflective output mirror assuming refractive index is 1.5' You may also want to consider Jeff Hecht's 'The Laser Guidebook', which does not seem to have a chapter on Laser Applications or the end of chapter quiz.

This book covers the major concepts involved in understanding how lasers perform and why they are useful. It goes into significant depth, but keeps the language from getting too technical, thus providing a "street smart" know-how about how these powerful light-emitters work. You may have to consult some more advanced texts for more detailed information about the more abstract concerns, but for a general use reference and an aid when explaining the material to others, this is pretty perfect.
