Program

1.- Introduction
Fundamental processes in radiation matter interaction: remarks on absorption,
spontaneous and stimulated emission. A simple model of lasers: rate  
equations. Laser
threshold. Relaxation oscillations. Brief description of most common  
lasers: He-Ne, Ar+,
dye, CO2, Nd-YAG, Semiconductor lasers; their properties and technical issues.

2.- Quantum and semiclassical model
Field quantification. The field, atom and interaction Hamiltonian. The  
rotating
wave approximation. Fluctuations and dissipation. The semiclassical  
model of radiation
matter interaction. Atomic susceptibility: gain and index of  
refraction. Homogeneous and
inhomogeneous broadening.

3.- Multimode lasers
Optical resonators: the ring and Fabry-Perot cavities. The boundary  
conditions.
Steady-sate solutions and their stability. Mode pulling. Mode-mode  
coupling. Active and
passive mode-locking. Dynamical behavior of multimode lasers.  
Homogeneous versus
inhomogeneous broadening. Lamb dip - Mode-hopping. Anti-phase oscillations.

4.- Single-mode lasers
The first and second laser thresholds. The exact solutions of Maxwell-Bloch
model. The uniform field limit. Classification of lasers. Q-switch.

5.- Some interesting laser systems
Laser with injected signal. Laser with optical feedback. Bidirectional ring
laser.Multi-transverse mode laser. Random lasers and more?..
