Résumé

Noise deamplification has been demonstrated in a CO₂ laser with modulated losses when it is driven near period-doubling bifurcations. Noise squeezing of the quadrature component up to 8 dB has been obtained on the first (T-2T) bifurcation while the noise for the in-phase component is increased by 19 dB. A similar phase sensitive behaviour was also observed on the second (2T-4T) bifurcation. Critical exponents for the signal amplification of 2.71 and 2.93 respectively were also obtained near these period-doubling bifurcations.
