Bolometric Night Sky Temperature and Subcooling of Telescope Structures
Ronald Holzlöhner, Stefan Kimeswenger, Wolfgang Kausch +1
Context. The term sky temperature is used in the literature in different contexts which often leads to confusion. In this work, we study , the effective bolometric sk…
Frequency chirped continuous-wave sodium laser guide stars
F. Pedreros Bustos, R. Holzlöhner, S. Rochester +3
We numerically study a method to increase the photon return flux of continuous-wave laser guide stars using one-dimensional atomic cooling principles. The method relies on chirping…
Raman-scattered laser guide star photons to monitor the scatter of astronomical telescope mirrors
F. P. A. Vogt, J. L. Álvarez, D. Bonaccini Calia +26
The first observations of laser guide star photons Raman-scattered by air molecules above the Very Large Telescope (VLT) were reported in June 2017. The initial detection came from…
Polarization-driven spin precession of mesospheric sodium atoms
Felipe Pedreros, Domenico Bonaccini Calia, Dmitry Budker +5
We report experimental results on the first on-sky observation of atomic spin precession of mesospheric sodium driven by polarization modulation of a continuous-wave laser. The mag…
Remote sensing of geomagnetic fields and atomic collisions in the mesosphere
Felipe Pedreros Bustos, Domenico Bonaccini Calia, Dmitry Budker +5
Magnetic-field sensing has contributed to the formulation of the plate-tectonics theory, the discovery and mapping of underground structures on Earth, and the study of magnetism in…
FEM investigation of leaky modes in hollow core photonic crystal fibers
J. Pomplun, R. Holzlöhner, S. Burger +2
Hollow-core holey fibers are promising candidates for low-loss guidance of light in various applications, e.g., for the use in laser guide star adaptive optics systems in optical a…
