Review title: Clarity problem in explanation of equations
Product review: This book looks and IS good when it comes down to going through complicated optical gain calculations. However, I feel the book expects reader to know important and advanced fundamentals of lasers which it does not go through in the book and may prove disadvantage to both advanced and beginner researchers interested in semiconductor lasers. The book includes many complex equations but they are, in my opinion, not explicitly explained in the text. In addition, what I found most disappointing about the book is that there were no examples to demonstrate gain calculations on any material (like GaAs-AlGaAs etc), which would really help in modeling a quantum well structure.
