Laser : Fundamentals. (Optique Pour l'Ingénieur : Lasers et optique non linéaire)

Balembois François

After a review, we approach the principles of correlation between light and material and conditions which lead to the amplification of light. Then, we treat the oscillator laser which is the association of a resonant hole and a middle booster of light. We describe finally the devices which are behind the word of "laser": oscillators and amplifiers, solid, liquid lasers (colouring agents) or gaseous.
