Anti-reflection coating with mullite and Duroid for large-diameter cryogenic sapphire and alumina optics
Kana Sakaguri, Masaya Hasegawa, Yuki Sakurai +10
We developed a broadband two-layer anti-reflection (AR) coating for use on a sapphire half-wave plate (HWP) and an alumina infrared (IR) filter for the cosmic microwave background…
Critical Power for Temporal-Pulse Collapse in Third-Harmonic Generation
Wataru Komatsubara, Kuniaki Konishi, Junji Yumoto +1
The self-trapping critical power of light propagation is one of the key physical quantities characterizing nonlinear-beam propagation. Above the critical power, the spatial and tem…
Probing Cosmic Inflation with the LiteBIRD Cosmic Microwave Background Polarization Survey
LiteBIRD Collaboration, E. Allys, K. Arnold +188
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
A Large Diameter Millimeter-Wave Low-Pass Filter Made of Alumina with Laser Ablated Anti-Reflection Coating
Ryota Takaku, Qi Wen, Scott Cray +14
We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) made with laser-ablated sub-wavelength structures (SWS). The filter has be…
Overview of the Medium and High Frequency Telescopes of the LiteBIRD satellite mission
L. Montier, B. Mot, P. de Bernardis +232
LiteBIRD is a JAXA-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the Univer…
LiteBIRD: JAXA's new strategic L-class mission for all-sky surveys of cosmic microwave background polarization
M. Hazumi, P. A. R. Ade, A. Adler +233
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
Concept Design of Low Frequency Telescope for CMB B-mode Polarization satellite LiteBIRD
Y. Sekimoto, P. A. R. Ade, A. Adler +232
LiteBIRD has been selected as JAXA's strategic large mission in the 2020s, to observe the cosmic microwave background (CMB) -mode polarization over the full sky at large angular…
Broadband, millimeter-wave anti-reflective structures on sapphire ablated with femto-second laser
R. Takaku, S. Hanany, H. Imada +13
We designed, fabricated, and measured anti-reflection coating (ARC) on sapphire that has 116% fractional bandwidth and transmission of at least 97% in the millimeter wave band. The…
Tunable third harmonic generation in the vacuum ultraviolet region using dielectric nanomembranes
Kuniaki Konishi, Daisuke Akai, Yoshio Mita +3
Tunable coherent light sources operating in the vacuum ultraviolet (VUV) region in 100-200-nm (6-12 eV) wavelength range have important spectroscopic applications in many research…
Updated design of the CMB polarization experiment satellite LiteBIRD
H. Sugai, P. A. R. Ade, Y. Akiba +216
Recent developments of transition-edge sensors (TESs), based on extensive experience in ground-based experiments, have been making the sensor techniques mature enough for their app…
Time-dependent Hartree-Fock study of electron-hole interaction effects on high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We investigate the multielectron effects on high-harmonic generation from solid-state materials using the time-dependent Hartree-Fock theory. We find qualitative change in harmonic…
Trajectory analysis of high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We theoretically study high-harmonic generation (HHG) from solids driven by intense laser pulses using a one-dimensional model periodic crystal. By numerically solving the time-dep…
