This course provides an introduction to the physics of lasers and some applications. It covers fundamental properties of light and its behavior in the presence of matter, the analysis of resonant cavities and light oscillation and amplification, and the physics of lasers and their properties. The course will address topics in fundamentals of electromagnetic theory, propagation of light, coherence, optical resonators, light-matter interactions, atomic radiation and laser excitation.
Students in this course will learn the fundamental properties of light-matter interactions and light propagation, and will examine the principles of different kinds of lasers.
Pre-requisites: E&M, Undergraduate Physics, Modern Physics, Knowledge of Differential Equations, Linear & Complex Algebra, Matrix representations, Optics.
Monday and Wednesday, 5:30-6:45, P&A Room 184.
There are many useful texbooks that cover the topcis on the class.
The course will follow the order of topics in textbook by Joseph T. Verdeyen (Ch1-11), and cover several
topics in each chapter.
Laser Electronics (3rd Edition) by Joseph T. Verdeyen. The course will cover about Chapters 1-11, although we will not cover all the material in some chapters.
Homeworks problems will contain problems from this book.
Laser Physics: P. W. Milonni, J. H. Eberly.
Laser Fundamentals: William T. Silfvast.
Principles of Lasers : Orazio Svelto.
Quanutm Electronics: Amnon Yariv
Laser Physics: Anthony E. Siegman

There will be regular assignments of problem sets taken many from the
textbook
by E. Verdeyen, about one set per week.
The assignments will be given throughout the semester and will be posted in the Tentative Schedule about one week
before they are due. Homeworks must be turned in at the begining of the class at 5:30 pm on the due date.
Office hours: Monday 11:30 am -13:30 pm. You may also arrange a meeting for another time via email.
TA office hours: Tuesday 12-1 pm P&A Rm 40.
You may also arrange a meeting for another time via email.
The final grade will be based on the homework assignments, two midterm exams and a final exam. The contribution to the final grade is as follows:
Exam Dates (subject to change): Midterms, I September 26, and II November 7.
The Final Exam is comprehensive and is scheduled for Monday, December 10, 5:30-7:30 pm
The course will follow the order of textbook by Joseph T. Verdeyen (Ch1-11), and cover several topics in each chapter. Below is a tentative list of topics that will be covered. You can find the calendar for the course in the Tentative Schedule.
