Prerequisites
The Mathematical and Physical concepts given by the 1st Level Degree (Mechanics and Electromagnetism, Geometry and Algebra, Mathematical Methods courses). The concepts illustrated in the course of “Fotonica” (Photonics) are important but not essential
Learning outcomes
The aim of the course is to introduce the basics of Quantum Physics, study the Matter-Radiation Interaction and the physics behind LASERS.
Course contents
Wave-particle duality, experimental facts
Quantum Mechanics Postulates, Schrödinger Equation
Eigenvalue problems, some examples of representative potentials
Angular momentum, Hydrogen Atom and Periodic Table of Elements
Identical Particles, Spin, Fermions and Bosons Statistics
Time Independent Perturbation Theory
Time Dependent Potentials, Perturbative method
Electric Dipole interaction
Fermi Golden Rule
Absorption, Spontaneous and Stimulated Emission, Einstein’s A and B coefficients
Density Matrix, radiation-matter interaction
3- and 4-levels systems, rate equations
Optical resonators
Free running laser operation
Q-Switching and Mode-Locking regimes
Some representative example of lasers (Gas lasers, Solid-state lasers, Fiber Lasers, Semiconductor Lasers)

Reccomended or required readings
There are many wonderful books about the topics we will cover in this Course. A lot of them are available at the Faculty Library. I will not follow a specific textbook, but students can refer to:
A. Yariv. Quantum Electronics. Wiley.
D. J. Griffiths. Introduction to Quantum Mechanics (2nd Edition). Pearson Prentice Hall.
C.L. Tang. Fundamentals of quantum mechanics, for solid state electronics and optics. Cambridge University Press.
W. Koechner. Solid.State Laser Engineering (6th Edition). Springer. This book can be considered the "Holy Bible" of solid-state lasers Engineers.
Assessment methods
The final exam will consist of an oral discussion or in a written test aimed to verify the effective acquisition of the concepts introduced in the course.
