Offering a fresh take on laser engineering, Laser Modeling: A Numerical Approach with Algebra and Calculus presents algebraic models and traditional calculus-based methods in tandem to make concepts easier to digest and apply in the real world. Each technique is introduced alongside a practical, solved example based on a commercial laser. Assuming some knowledge of the nature of light, emission of radiation, and basic atomic physics, the text:

Explains how to formulate an accurate gain threshold equation as well as determine small-signal gain
Discusses gain saturation and introduces a novel pass-by-pass model for rapid implementation of "what if?" scenarios
Outlines the calculus-based Rigrod approach in a simplified manner to aid in comprehension
Considers thermal effects on solid-state lasers and other lasers with new and efficient quasi-three-level materials
Demonstrates how the convolution method is used to predict the effect of temperature drift on a DPSS system
Describes the technique and technology of Q-switching and provides a simple model for predicting output power
Addresses non-linear optics and supplies a simple model for calculating optimal crystal length
Examines common laser systems, answering basic design questions and summarizing parameters
Includes downloadable Microsoft^? Excel^? spreadsheets, allowing models to be customized for specific lasers

A Numerical Approach with Algebra and Calculus covers laser theory in an accessible way that can be applied immediately, and numerically, to real laser systems.
