Recently we have demonstrated the quantum nature of light in strongly laser driven atoms and we have shown how the process of high harmonic generation (HHG) can be used for the creation of highly non-classical light including optical Schrödinger ``cat'' states. Here, we investigate the quantum electrodynamics of the interaction incorporating collective effects and the back action of the HHG and Above Threshold Ionization (ATI) processes on the coherent state of the driving laser field. We show how the conditioning on HHG and ATI can lead to non-classical light states and we discuss the key parameters that can be used for controlling and characterizing these light states. Our findings anticipate the development of new methods that naturally lead to the creation of non-classical light with controllable quantum features for applications in quantum technology.
