Background-free Tracking of Ultrafast Hole and Electron Dynamics with XUV Transient Grating Spectroscopy
Vincent Eggers, Rafael Quintero-Bermudez, Kevin Gulu Xiong +1
Extreme ultraviolet (XUV) transient absorption (TA) and transient reflectivity (TR) spectroscopies enable element-specific insights into attosecond-timescale processes in solids. X…

Attosecond transient grating spectroscopy with near-infrared grating pulses and an extreme ultraviolet diffracted probe
Rafael Quintero-Bermudez, Lorenz Drescher, Vincent Eggers +2
Transient grating spectroscopy has become a mainstay among metal and semiconductor characterization techniques. Here we extend the technique towards the shortest achievable timesca…
