Lasers
Objectives
Aiming at the global aspects of lasers (principally solid-state lasers), lasers curricular unit will focus on the most important laser design concepts so that the students can understand and apply laser fundamentals to both their analyses and solar-pumped solid-state laser experiments in laboratory session. Students are expected to gain laser theory, up-to-date laser knowledge and essential laser design skills. Lasers curricular unit will enhance the interests of students on laser engineering by stressing the importance of innovation for successful engineering students.

Evaluation method
60% Theoretical Examination + 20% Laboratory Sessions and Reports Evaluations + 20% Laboratory Demostration Sessions and Homework Evaluations
Subject matter
Introduction to laser history, laser beam properties and laser applications. Basic principles like blackbody radiation, absorption, population inversion, laser oscillators, resonant cavity stability criteria, laser active media, laser gain, efficiencies and laser output powers will be discussed in the lecture sessions. Many homemade solid-sate laser pump cavities will all be demonstrated during laboratory sessions.
60% is attributed to laser theory examination. The laboratory session (20%) with solar-pumped laser experiments along with laser beam profile diagnostics will deepen considerably the student´s knowledge about laser engineering. Other 20% is based on student´s reports on experimental sessions and homework
