1. Results of aperture area comparisons for exo-atmospheric total solar irradiance measurements
Topic: Optical Physics
Published: 11/13/2013
Authors: Bettye C Johnson, Maritoni Abatayo Litorja, Joel B. Fowler, Eric L Shirley, James J Butler, Robert A Barnes
Abstract: Exo-atmospheric solar irradiance measurements made by the solar irradiance community since 1978 incorporate limiting apertures with diameters measured by a number of metrology laboratories using a variety of techniques. Knowledge of the aperture are ...

2. Spectral response and characterization of a high-efficiency upconvertor for single-photon-level detection
Topic: Optical Physics
Published: 10/18/2013
Authors: Paulina S Kuo, Oliver T Slattery, Yong-Su Kim, Jason S. Pelc, M. M. Fejer, Xiao Tang

3. Using radiation pressure for measurement of high-power laser emission
Topic: Optical Physics
Published: 10/15/2013
Authors: Paul A Williams, Joshua Aram Hadler, Robert Lee, Frank Maring, John H Lehman
Abstract: We demonstrate a paradigm in absolute laser radiometry where a laser beam's power can be measured from its radiation pressure. Using an off-the-shelf high-accuracy mass scale and a 500 W Yb-doped fiber laser and a 92 kW CO2 laser, we show preliminary ...

4. Strong Casimir force reduction by metallic surface nanostructuring
Topic: Optical Physics
Published: 9/27/2013
Authors: Francesco Intravaia, Stefan T. Koev, Il Woong Jung, Albert A. Talin, Paul S Davids, Ricardo Decca, Vladimir A Aksyuk, Diego A. R. Dalvit, Daniel Lopez
Abstract: The Casimir force is a quantum-mechanical interaction arising from vacuum fluctuations of the electromagnetic (EM) field and is technologically significant in micro- and nanomechanical systems. Despite rapid progress in nanophotonics, the goal of e ...

5. Spectral response of an upconversion detector and spectrometer
Topic: Optical Physics
Published: 9/17/2013
Authors: Paulina S Kuo, Oliver T Slattery, Yong-Su Kim, Jason S. Pelc, M. M. Fejer, Xiao Tang
Abstract: We theoretically and experimentally investigate the spectral response of an upconversion detector and discuss implications for its use as an infrared spectrometer. Upconversion detection is based on high-conversion-efficiency sum-frequency generation ...

6. Harnessing 3D Scattered Optical Fields for sub-20 nm Defect Detection
Topic: Optical Physics
Published: 6/24/2013
Authors: Bryan M Barnes, Martin Y Sohn, Francois R. (Francois) Goasmat, Hui Zhou, Richard M Silver, Abraham Arceo
Abstract: Experimental imaging at =193 nm of sub-resolved defects performed at several focus positions yields a volume of spatial and intensity data. Defects are located in a differential volume, given a reference, with up to 5x increase in sensitivity ...

7. A comb-calibrated FMCW LADAR for absolute distance measurements
Topic: Optical Physics
Published: 6/15/2013
Authors: Esther Baumann, Fabrizio Raphael Giorgetta, Ian R Coddington, Laura C Sinclair, Kevin Otis Knabe, William C Swann, Nathan Reynolds Newbury
Abstract: We present a comb calibrated frequency-modulated continuous wave (FMCW) LADAR system for absolute distance measurements to diffuse or specular surfaces. The FMCW LADAR uses a MEMS-based external cavity laser that is swept quasi-sinusoidally over 1 TH ...

8. Modulated photocurrent spectroscopy of CdTe/CdS solar cells-equivalent circuit analysis
Topic: Optical Physics
Published: 5/20/2013
Authors: Behrang H Hamadani, John F Roller, Kounavis Panagiotis, Nikolai B Zhitenev, David J Gundlach
Abstract: We have used the technique of photocurrent modulated spectroscopy to investigate the dynamic response of charge carrier transport in thin film CdTe/CdS solar cells as a function of light bias and temperature over a broad excitation frequency range. T ...

9. Random testing reveals excessive power in commercial laser pointers
Topic: Optical Physics
Published: 5/1/2013
Authors: Joshua Aram Hadler, Edna L Tobares, Marla L Dowell
Abstract: In random testing of 122 commercial laser pointers, we observed that 89.7 % of green pointers and 44.4 % of red pointers were not in compliance with the Code of Federal Regulations, producing laser power in excess of the Accessible Emission Limit at ...

10. Accurate, inexpensive testing of handheld lasers for safe use and operation
Topic: Optical Physics
Published: 3/7/2013
Authors: Marla L Dowell, Joshua Aram Hadler
Abstract: An accurate, inexpensive test bed for measurements of optical power emitted from handheld lasers is described. Our test bed consists of a thermopile detector, bandpass optical filters, an adjustable iris, and self-centering holders for mounting of th ...
