This course covers the basic principles of laser oscillation. Specific topics include propagation of rays and Gaussian beams in lens-like media, optical resonators, spontaneous and stimulated emission, interaction of optical radiation and atomic systems, conditions for laser oscillation, homogeneous and inhomogeneous broadening, gas lasers, solid state lasers, Q-switching and mode locking of lasers.

The best aspects of the course included the cutting-edge lessons on compressed sensing and the kind professor. The topic was very interesting and students got to learn the practical aspect of things as well. The worst aspects of the course included the chal enging and comprehensive homework assignments, many of which seemed to have a strong mathematical base. The course would improve if there were more programming assignments and more chal enging homework assignments to help student grapple with the more difficult content. Prospective students should have some math background in this highly recommended course.

According to many students, the course material presented was fascinating and the professor was a master of the subject matter. The class was comprised of both lectures and labs, which prevented monotony. Also, the labs included hands-on experience with designing mixed LVSI devices. However, students said it was very easy to fall behind in this course because of the challenging material and pace. In addition, some of the tools were not properly configured for the project, which made it difficult to complete. Suggestions for improvement include: office hours or a TA, an official textbook, a slower lab and lecture pace, and better tools. Prospective students interested in microelectronic design should take this class.

The best aspects of this class included the interesting course topics, the hands on labs, and the manageable workload. Students felt that the course had little structure and that assignment expectations were unclear. The professor was hard to understand and not enough time was given for assignments to be completed. Suggestions for improvement included having more opportunities for feedback via graded assignments and providing students with a comprehensive syl abus at the beginning of the course. Prospective students should have a background in optics and be familiar with CAD. Prospective students should also start final projects as soon as possible.
