High-harmonic generation is a process where intense coherent laser pulses interact with electrons in a gas or solid medium, resulting in attosecond light pulses. We, that is the groups of Ido Kaminer and Oren Cohen and our group at the Technion, have asked ourselves: What will happen if we replace the coherent laser pulses by nonclassical light?<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

This question seems academic, but recent developments in laser physics and quantum optics enable the generation of so-called bright squeezed vacuum (BSV). In this quantum state of light, the mean electric field is zero, but the fluctuations of the field are huge – so huge that HHG can be driven just by fluctuations! In our first theory work by Alexey Gorlach et al. in Nature Physics<\/a>, we show that theoretically BSV-driven HHG results in higher HHG photon energies and higher efficiency. In a second theory work by Matan Even Tzur et al. in Nature Photonics<\/a>, we demonstrate that if the coherent laser pulses are slightly squeezed, a new kind of force is emerging which distorts the electron dynamics and the attosecond light pulses – the “photon statistics force”.<\/p>\n\n\n\n

Our research is building a bridge between strong-field physics and quantum optics, two fields that seem very different from each other. Stay tuned for further developments!<\/p>\n","protected":false},"excerpt":{"rendered":"
