  • A simple method is demonstrated for high-order harmonic generation with fully controlled (linear, elliptical and circular) polarization. Its conversion efficiency is comparable to those of conventional high-order harmonic methods. This technique potentially has a broad range of applications from ultrafast circular dichroism to attosecond quantum optics.

  • In measurements that employ phase retrieval algorithms, such as coherent diffraction imaging, reconstruction of one-dimensional signals is challenging due to ambiguity issues. Here, the authors demonstrate super-resolution coherent imaging of one-dimensional objects by utilizing sparsity prior information.

  • The authors introduce the concept of real-synthetic symmetries and use it as a tool to derive selection rules in seemingly symmetry-broken strong-field interactions. These symmetries and their corresponding selection rules can be applied in various systems form harmonic generation to topological photonics

  • Understanding the photoelectron emission time after the interaction of photon with atoms and molecules is of fundamental interest. Here the authors examine the role of partial waves to the photoionization phase shift of atoms using an attosecond clock and electron-ion coincidence spectroscopy.
