OSE5525 - Laser Engineering

OSE5525_banner 6-2020

Principles of laser amplification and oscillations; design of lasers; general characteristics of excitation systems.

This is a single semester course on Lasers. Although currently called “Laser Engineering” it is being renamed “Principals of Lasers” and is a new introductory course on lasers. It is suitable for students with backgrounds in physics, electrical engineering, chemistry and other disciplines who require a fundamental knowledge of lasers and how they operate. For students at the College of Optics it is considered the primary introductory laser course and is now part of the core curriculum. The course covers the basic physics of laser operation, and includes understandings of resonator theory, pulsed and continuous wave operation of lasers. Most popular lasers are described, as well as a pulsed techniques such as Q-switching, mode-locking and harmonic generation. The student is also introduced to the exciting types of new lasers being developed. After taking this course, students should be able to take more advanced courses in Lasers. It is the pre-requisite for the laboratory course, OSE 6526 Laser Laboratory.
