Orbital-selective time-domain signature of nematicity dynamics in the charge-density-wave phase of LaEuSrCuO
Martin Bluschke, Naman K. Gupta, Hoyoung Jang +23
Understanding the interplay between charge, nematic, and structural ordering tendencies in cuprate superconductors is critical to unraveling their complex phase diagram. Using pump…
Ultrafast X-ray imaging of the light-induced phase transition in VO2
Allan S. Johnson, Daniel Pérez-Salinas, Khalid M. Siddiqui +26
Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed ou…
4D visualization of the photoexcited coherent magnon by an X-ray free electron laser
Hoyoung Jang, Hiroki Ueda, Hyeong-Do Kim +12
X-ray free electron lasers (XFEL) create femtosecond X-ray pulses with high brightness and high longitudinal coherence allowing to extend X-ray spectroscopy and scattering techniqu…
Single-shot terahertz spectrometer using a microbolometer camera
Dogeun Jang, Hanran Jin, Ki-Yong Kim
We demonstrate a single-shot terahertz spectrometer consisting of a modified Mach-Zehnder interferometer and a microbolometer focal plane array. The spectrometer is simple to use a…
Multicycle terahertz pulse generation by optical rectification in LiNbO, LiTaO, and BBO crystals
Dogeun Jang, Ki-Yong Kim
We report multicycle, narrowband, terahertz radiation at 14.8 THz produced by phase-matched optical rectification of femtosecond laser pulses in bulk lithium niobate (LiNbO) cr…
Generation of 0.7 mJ multicycle 15 THz radiation by phase-matched optical rectification in lithium niobate
Dogeun Jang, Jae Hee Sung, Seong Ku Lee +2
We demonstrate efficient multicycle terahertz pulse generation at 14.6 THz from large-area lithium niobate crystals by using high-energy (up to 2 J) femtosecond Ti:sapphire laser p…
Simplified single-shot supercontinuum spectral interferometry
Dhruvit Patel, Dogeun Jang, Scott W. Hancock +2
We have experimentally demonstrated a simplified method for performing single-shot supercontinuum spectral interferometry (SSSI) that does not require pre-characterization of the p…
Scalable terahertz generation by large-area optical rectification at 80 TW laser power
Dogeun Jang, Chul Kang, Seong Ku Lee +3
We demonstrate high-energy terahertz generation from a large-aperture (75 mm diameter) lithium niobate wafer by using a femtosecond laser with energy up to 2 J. This scheme utilize…
Simplified Chirp Characterization in Single-shot Supercontinuum Spectral Interferometry
DinhDuy Tran Vu, Dogeun Jang, Ki-Yong Kim
Single-shot supercontinuum spectral interferometry (SSSI) is an optical technique that can measure ultrafast transients in the complex index of refraction. This method uses chirped…
Spectral Characterization of a Microbolometer Focal Plane Array at Terahertz Frequencies
D. Jang, M. Kimbrue, Y. J. Yoo +1
We have developed a method to characterize the spectral response of an uncooled microbolometer focal plane array at a broad range of terahertz (THz) frequencies (4~50 THz). This is…
