Abstract: We demonstrated parametric wavelength conversion between frequency-controlled two infrared (frequency fixed pumping and tunable (controlled by spectral drill cavity) seeding) beams and sub ...

Abstract: Through an efficient linearization of the optical frequency chirps of a quantum cascade laser (QCL), we demonstrate and compare two methods of coherent ranging in the long-wave infrared ...

Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright ...
