Physical foundations of laser radiation

Date & Time: April 30th (3:00 PM - 4:00 PM), May 1st (9:00 AM - 11:00 AM), May 3rd (11:30 AM - 12:30 PM) and May 4th (10 AM - 11 AM)
Course Level: Introductory
Instructor: Prof. Angela M. Guzmán, CREOL, University of Central Florida (United States)

The course is intended to review fundamental concepts, basic structure and characteristics of diverse laser sources. It serves as an overview on well-established principles and techniques, whose applications will be covered in depth in courses by other lecturers. The course covers the following topics: (i) Laser physics, general introduction: foundations and properties of laser radiation. (ii) Basic principles of lasers: characteristics, pumping and optical resonator. (iii) Control of laser light: bandwidth, cavity modes, q-switching and mode-locking. (iv) Types of lasers: from ruby laser to semiconductor lasers and optical fiber laser.

Light sources characterization and coherence properties

Date & Time: April 30th 2012 (4:30 PM - 5:30 PM) and May 2nd 2012 (2:00 PM - 4:00 PM)
Course Level: Introductory
Instructor: Prof. Maria L. Calvo, Universidad Complutense de Madrid, Spain

Light sources characterization is studied from the well-established theory of partial coherence of light established in the early 50’s of the 20th C. and the previous theoretical approach as introduced by Albert Einstein in 1917 with his work on the quantum theory of radiation. The lecturer will present a revision of selected key earlier experiments developed in the 50’s and 60’s of the 20th C. with the aim to characterize the degree of spatial and temporal coherence of a luminous source and applications.

Laser resonators (conventional & holographic) & Laser power measurement

Date & Time: May 1st (11:30 AM - 12:30 PM), May 3rd (9:00 AM - 11:00 AM) and May 4th (9:00 AM - 10:00 AM) 
Course Level: Intermediate
Instructor: Prof. Eric Rosas, National Center of Metrology, CENAM, Mexico

The course is intended to review the fundamental concepts on conventional laser resonators such as stable and unstable cavities, laser cavities geometries, Gaussian modes propagation parameters: spot size and radius of curvature, ABCD propagation matrices; as well as some holographic laser resonators principles such as the four-wave mixing non-linear phenomena used in high power extraction solid-state lasers. Also some fundamental concepts on primary radiometry related to laser power measurement are to be presented, such as traceability, accuracy, uncertainty estimation, and measurement techniques and required instrumentation.
