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…
Single-shot Ultrafast Imaging via Spatiotemporal Division of Femtosecond Laser Pulses
Sarang Yeola, Donghoon Kuk, Ki-Yong Kim
We have developed a single-shot imaging technique that can capture ultrafast events occurring on femtosecond to picosecond time scales. The technique is based on an optical pump-pr…
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…
THz generation by optical Cherenkov emission from ionizing two-color laser pulses
Luke A. Johnson, John P. Palastro, Thomas M. Antonsen +1
Two-color photoionization produces a cycle-averaged current driving broadband, conically emitted THz radiation. We investigate, through simulation, the processes determining the an…
Summary report of working group 5: Beam and radiation generation, monitoring, and control
Mike Church, Ki-Yong Kim
This paper summarizes the activities and presentations of Working Group 5 of the Advanced Accelerator Concepts Workshop held at Annapolis, Maryland in June 2010. Working Group 5 to…
