481/581-2E Laser Physics I (Fall 2008)

 

Lecture: Tuesday, Thursday 2:00-3:15 pm, Campbell Hall (CH) Room 304.

Professor: Sergey B. Mirov, Office Hours: Tu, 10:00am-12:00 n in CH 421B or by appointment (4-8088, mirov@uab.edu).

Course Text:  Lasers and Electro-Optics, Fundamentals and Engineering by Christopher Davis

Supplemental Books: Lasers and Electro-Optics by Christopher Davis (LEO) is the only textbook that will be required.  However, the textbook material will be significantly augmented by additional in-class lecture material, particularly in the area of lasers and applications of laser spectroscopy.  The exams and homework will cover material from LEO and the in-class lectures.  For students that would like sources of additional reading (again, this is not necessary, but some students like to have additional reading sources), other excellent books include: (i) Fundamentals of Photonics by B.E.A. Saleh & M.C. Teich; (ii) Laser Fundamentals by William Silfvast, (iii) Optical Electronics by Amnon Yariv; (iiii) Laser Spectroscopy by Wolfgang Demtroder; (iiiii) Principles of Lasers by Orazio Svelto.

Homework: Homework problems will be assigned weekly, at the end of class and will be due the following week at the beginning of the class to verify your continuing effort. It is absolutely critical to work these problems yourselves when they are assigned, since this will help to lock in understanding of the physical principles learned from class and the textbook and develop problem solving skills which will be necessary for any type of success on the exams.

Exams: The exams will be based on problems related to (but often with important differences) homework problems and problems discussed in class.  The intent of the exam problems will be to test your understanding of physics principles and to test your ability to apply these principles to practice. The exams will be graded on a step-by-step basis, with partial credit awarded for correct steps and techniques even if the answer is wrong.  Full credit will be awarded only if the right answer is obtained for the right reason.

 

Students of PH581 will be usually assigned additional (with respect to students of PH481) homework and exam problems.

 

Related UAB core learning outcomes: Students successfully completing this course will demonstrate knowledge of fundamentals of laser physics, the characteristics of laser radiation, and individual types of lasers, including optically pumped dielectric crystal lasers, atomic gas lasers, molecular gas lasers, and semiconductor lasers.  

 

Course learning objectives: 

·                     Demonstrate knowledge and understanding of fundamental aspects of laser physics and engineering of lasers of all kinds, including fundamental physics of stimulated emission process and laser amplifiers, optical resonators, characteristics of laser radiation and methods for controlling it, as well as practical aspects of optics that pertain to an understanding of these subjects.  

·                     Demonstrate ability to apply the knowledge of the fundamental aspects of laser physics as well as quantitative reasoning and mathematical analysis skills to effectively solve problems.

 

Measurement of learning objectives: Homework problem sets and exams will be used regularly to measure understanding of the fundamental concepts presented as well as students’ abilities to apply this understanding to problems in laser physics. Both, problem sets and exams also provide an opportunity to evaluate the progression of students’ understanding of physical concepts and problem solving skills.
