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…
Selective laser ablation of metal thin films using ultrashort pulses
Byunggi Kim, Han Ku Nam, Shotaro Watanabe +5
Selective thin-film removal is needed in many microfabrication processes such as 3-D patterning of optoelectronic devices and localized repairing of integrated circuits. Various we…
Free-space transfer of comb-rooted optical frequencies over an 18 km open-air link
Hyun Jay Kang, Jae-Won Yang, Byung Jae Chun +4
Phase-coherent transfer of optical frequencies over a long distance is required for diverse photonic applications, including optical clock signal dissemination and physical constan…
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…
Surface Plasmon Assisted Gentle Ablation of Nanostructures by Femtosecond Oscillator
Liping Shi, Bianca Iwan, Quentin Ripault +16
We experimentally demonstrate the use of subwavelength optical nanoantennae to assist the gentle ablation of nanostructures directly using ultralow fluence from a Ti: sapphire osci…
