Synopsis
Lasers have become ubiquitous in our daily lives. From DVD players to bar code scanners, printers, or even in medicine, laser-based applications are countless. Not to mention the  pivotal role that lasers are playing in science and in state of the art industrial processes. But  what are the characteristics of lasers that make them so broadly used?
In this brief course we will answer this question by describing the physics of laser systems and the properties of laser radiation. We will also explain the basic interactions between  laser light and materials, and we will give examples of applications where lasers are the  enabling technology.
This course is intended for PhD students who anticipate working with lasers. No background in lasers is required. Emphasis is placed on the physical interpretation of lasers and on their applications, with mathematics kept at a minimum.

Syllabus
The course develops in 12 hours in the classroom.  
- Fundamentals of lasers:  lasers, laser radiation characteristics, laser types
- Interaction of lasers with materials: absorption, dispersion, photophysical processes, photochemical processes
- Lasers at IIT: 3D microfabrication, nanoparticle generation, photolithography, surface structuration, optical characterization

The examination consists in a brief research project proposal or in an oral presentation.
