… have a directional-hemispherical (0°/h) reflectance of 94 ± 4 ppm (k = 2) at 660 nm and are superhydrophilic. O2 and CF4 plasma … treated VACNTs have a 0°/h reflectance of 163 ± 7 ppm (k = 2) at 660 nm and are superhydrophobic with a contact angle of …

Infrared and visible laser spectroscopy for highly-charged Ni-like ions

April 12, 2017
Author(s)
Yuri Ralchenko
Application of visible or infrared (IR) lasers for spectroscopy of highly-charged ions (HCI) has not been particularly extensive so far due to a mismatch in typical energies. We show here that the energy difference between the two lowest levels within the

Author(s)
Alec J. Weiss, Jeanne Quimby, Rodney Leonhardt, Benjamin Jamroz, Dylan Williams, Kate Remley, Peter Vouras, Atef Elsherbeni
This paper discusses the configuration and control of a new millimeter wave over-the-air measurement system. This system provides unparalleled measurement accuracy, flexibility, and the ability to bound uncertainties on its measurements. The system also

240 Hz linewidth Brillouin laser from a microrod whispering gallery mode resonator

September 29, 2015
Author(s)
William Loh, Aurelien C. Coillet, Frederick N. Baynes, Scott B. Papp, Scott A. Diddams, Joe Becker
We demonstrate an ultra-low noise laser that oscillates based on the stimulated Brillouin scattering nonlinearity in an optical microresonator. Our Brillouin laser employs a microrod resonator whose larger mode volume compared to conventional resonators
