Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens
Shaul Hanany, Scott Cray, Samuel Dietterich +12
We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designe…
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…
Picosecond Laser Ablation of Millimeter-Wave Subwavelength Structures on Alumina and Sapphire
Qi Wen, Elena Fadeeva, Shaul Hanany +4
We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effect…
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…
PICO: Probe of Inflation and Cosmic Origins
S. Hanany, M. Alvarez, E. Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is a proposed probe-scale space mission consisting of an imaging polarimeter operating in frequency bands between 20 and 800 GHz. W…
PICO: Probe of Inflation and Cosmic Origins
Shaul Hanany, Marcelo Alvarez, Emmanuel Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is an imaging polarimeter that will scan the sky for 5 years in 21 frequency bands spread between 21 and 799 GHz. It will produce f…
Optical Design of PICO, a Concept for a Space Mission to Probe Inflation and Cosmic Origins
Karl Young, Marcelo Alvarez, Nicholas Battaglia +28
The Probe of Inflation and Cosmic Origins (PICO) is a probe-class mission concept currently under study by NASA. PICO will probe the physics of the Big Bang and the energy scale of…
PICO - the probe of inflation and cosmic origins
Brian Sutin, Marcelo Alvarez, Nicholas Battaglia +31
The Probe of Inflation and Cosmic Origins (PICO) is a NASA-funded study of a Probe-class mission concept. The top-level science objectives are to probe the physics of the Big Bang…
Broadband Millimeter-Wave Anti-Reflection Coatings on Silicon Using Pyramidal Sub-Wavelength Structures
Karl Young, Qi Wen, Shaul Hanany +5
We used two novel approaches to produce sub-wavelength structure (SWS) anti-reflection coatings (ARC) on silicon for the millimeter and sub-millimeter (MSM) wave band: picosecond l…
Millimeter-Wave Broadband Anti-Reflection Coatings Using Laser Ablation of Sub-Wavelength Structures
Tomotake Matsumura, Karl Young, Qi Wen +7
We report on the first use of laser ablation to make sub-millimeter, broad-band, anti-reflection coatings (ARC) based on sub-wavelength structures (SWS) on alumina and sapphire. We…
