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…
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…
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…
Geometrical analysis of Kerr-lens mode-locking for high-peak-power ultrafast oscillators
Peiyu Xia, Makoto Kuwata-Gonokami, Kosuke Yoshioka
Ultrashort pulses from Kerr-lens mode-locked oscillators have inspired a variety of applications. The design and alignment of these laser resonators have thus far been theoreticall…
