Abstract

Due to its simple level structure, helium 4 is particularly attractive to investigate original scenario for nonlinear light-atom interaction. We illustrate this feature by two examples: i) the demonstration of an original CPT-enhanced phase sensitive amplifier for light, which has been used to generate a squeezed vacuum and, ii) the originality of spin noise spectroscopy in metastable helium 4.
