Optics-less beam control of EUV high harmonics generated from solids
Byunggi Kim, Seungman Choi, Yong Woo Kim +3
High harmonics generation (HHG) of coherent extreme ultraviolet (EUV) radiation enables ultrafast pump-probe spectroscopy with attosecond-scale timing resolutions. Yet beam control…
Extraction of higher-order nonlinear electronic response to strong field excitation in solids using high harmonic generation
Seunghwoi Han, Lisa Ortmann, Hyunwoong Kim +9
State-of-the-art experiments employ strong ultrafast optical fields to study the nonlinear response of electrons in solids on an attosecond time-scale. Notably, a recent experiment…
Spectral Interference in High Harmonic Generation from Solids
Yong Woo Kim, Tian-Jiao Shao, Hyunwoong Kim +5
Various interference effects are known to exist in the process of high harmonic generation (HHG) both at the single atom and macroscopic levels. In particular, the quantum path dif…
Comb-rooted multi-channel synthesis of ultra-narrow optical frequencies of few Hz linewidth
Heesuk Jang, Byung Soo Kim, Byung Jae Chun +5
We report a multi-channel optical frequency synthesizer developed to generate extremely stable continuous wave lasers directly out of the optical comb of an Er-doped fiber oscillat…
