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?..
