RESUMO

We present in this work the project and construction of an Optical Parametric Oscillator ( OPO ) , showing the quantum behavior in the intensity correlation of signal and idler beams, generated from a 532 nm pump. We have also studied, in a second set-up, the quantum noise compression in the pump beam reflected from an OPO cavity, obtaining 38% of noise reduction below the vacuum fluctuations in the quadrature of a 1064 nm beam coming from a Nd: YAG laser. Finally, we observed the pattern formation in the output beams for transverse degenerate cavities ( confocal and concentric ) and we show, for the first time to our knowledge, the transverse multimode behavior in the quantum correlation of a confocal OPO
