| Popis: | We will present results that demonstrate squeezed light source based on Four Wave Mixing (FWM) in hot Potassium vapor. Squeezed light with the noise level of -6 dB below standard quantum limit is observed in the difference signal between correlated probe and conjugate beams, generated via FWM in potassium vapor. The vapor is contained in the vacuum K cell. For generating FWM we use nearly co-propagating pump and probe beam in a double Λ atomic scheme, which is similar to schemes used to demonstrate sqeezing in KD and in K. Obtained level of squeezing is improvement from the previous results for squeezing in potassium. |
