Description

I will present the recent achievements on the synthesis of Quantum Optics with Strong field laser physics. Specifically, I will describe how the strong-field laser-matter interaction can lead to the generation of non-classical light-states which carry the information of the ultrafast dynamics of the interaction.

Summary

Strong laser-field physics and quantum-optics, are two disjoined major research domains founded on the classical and quantum description of the electromagnetic radiation, respectively. The former deals with interactions of matter with strong laser fields while the later mainly with interactions of matter with weak laser fields. The research domain of "Strong-Laser-Field" physics led to groundbreaking discoveries in directions ranging from relativistic electron acceleration to attosecond science [1]. On the other hand, the research domain of "Quantum Optics" opened the way for fascinating achievements in the field of Quantum Technology [2] advancing studies ranging from quantum communication, information and computation to high precision interferometry applied for the detection of gravitational waves.

Despite the tremendous progress, the research domains of Quantum optics and Strong laser-field physics remained disconnected over the years. Here, I will present their synthesis. Specifically, I will describe how the strong-field laser-matter interaction can lead to the generation of non-classical light-states which carry the information of the ultrafast dynamics of the interaction [3-5]. Utilizing a novel detection method named "quantum spectrometer" [4], these light states have been used to recover the high-harmonic spectrum generated in gases [4] and crystals [5], and reveal information which is inaccessible by conventional approaches.
