    Real lasers show intrinsic noise well above the standard quantum noise limit. We review the properties of lasers and of techniques to suppress this noise. Experimental results of electro-optic feedback techniques and of squeezing in a second harmonic generator are presented. Finally we show that the optimum light source could well be a cascade of different cavities, each one performing a specific task in the noise suppression
