Composition of Terrestrial Exoplanet Atmospheres from Meteorite Outgassing Experiments

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Maggie A. Thompson, Myriam Telus, Laura Schaefer, Jonathan J. Fortney, Toyanath Joshi | Summary: Terrestrial exoplanets likely form initial atmospheres through outgassing during and after accretion, although there is currently no first-principles understanding of how to connect a planet’s bulk composition to its early atmospheric properties. Important […]

Quasi-static Optical Parametric Amplification

Posted by Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Marc Jankowski, Nayara Jornod, Carsten Langrock, Boris Desiatov, Alireza Marandi | Summary: High-gain optical parametric amplification is an important nonlinear process used both as a source of coherent infrared light and as a source of nonclassical light. In this work, we experimentally demonstrate an approach to optical […]

Efficient Octave-Spanning Parametric Down-Conversion at the Picojoule Level

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Marc Jankowski, Nayara Jornod, Carsten Langrock, Boris Desiatov, Alireza Marandi | Summary: The generation and amplification of photons by parametric down-conversion in quadratic nonlinear media is used as a source of entangled photons, squeezed light, and short optical pulses at difficult to access wavelengths. Optical nonlinearities are […]
