Research Interests & Publications:
Fields of research:
- High laser-field physics
- Ultrafast optics & attosecond science
- Super-resolution imaging
- We have been developing sources of extreme ultraviolet pulses with attosecond to femtosecond duration (femto and atto correspond to 10-15 and 10-18, respectively) and with fully controllable polarization. We employ these unique sources for exploring ultrafast dynamics in magnetism, chirality, and of charge and spin currents in atoms, molecules and solids.
- Progress in super-resolution microscopy (the topic of the 2014 Nobel Prize in chemistry) has been pushing forward many fields in science, medicine and technology. While proliferation of super-resolution techniques have been established, they all suffer from relatively long acquisition time (~0.1 seconds) that also limits the imaging temporal resolution. We develop ultrafast super-resolution microscopy!
- We discovered, explore and employ long-lived optically-induced atmospheric waveguides.
