  • Light absorption in matter often induces ultrafast electron dynamics within the system. Here, the authors record a femtosecond movie of the electron density of an argon ion as it oscillates in a quantum beat of two fine-structure states.

  • Isolated attosecond pulses (IAPs) in the extreme-ultraviolet range are generated by the interaction of half-cycle mid-infrared pulses with gas (Xe, Kr or Ar) and solid media (quartz). The energy of the IAPs is optically tunable over an octave.

  • A mechanically compliant and robust sensing material is essential for accurate and reliable thermal sensing. Here, the authors report the use of elastic organic crystals as fluorescence-based thermal sensors that cover a wide range of temperatures with complete retention of the sensor’s elasticity.

  • Near-infrared femtosecond laser pulses are sent to a Si or ZnO crystal to generate high-harmonic waves via static or transient field-induced optical nonlinearities. The beam profile of the high-harmonic emission is controlled by electronic methods.

  • Ultrafast pulses with controlled parameters are desirable in many applications including probing materials and their interaction with light. Here the authors demonstrate a technique for polarization control of XUV beam using high-harmonic generation and polarization shaping.

  • High harmonic generation is a nonlinear optical phenomena and HHG from solid offers challenges and advantages over dilute media like gases. Here the authors report HHG from metallic thin film of titanium nitride and discuss the role of intraband current to HHG.

  • Absorption lineshape of H2 is coherently controlled by using intense near-infrared laser pulses. Depending on the time delay between the near-infrared and extreme ultraviolet pulses, the profiles display a Lorentzian or an asymmetric Fano lineshape.

  • Transient absorption spectroscopy is used to identify the structural characteristics of the atoms and molecules. Here the authors used extreme ultraviolet transient absorption spectroscopy to identify the Rydberg state symmetry of aligned molecules.

  • Conical intersections, a hallmark of polyatomic molecules, can be induced with light, leading to new reaction pathways. Here, the authors show that intense fields can create complex, beyond-conical intersections even in diatomics, resulting in an unexpected angular distribution of fragment ions.
