摘要： An ultra-stable short pulse remote sensor having extended temporal coherence for long range sensing. The sensor provides unique target signatures from an ultrashort pulse after it has interacted with a target at range by measuring the spectral amplitude and phase of the pulse. Accordingly, coherent detection of targets at long ranges can be performed with reduced power.

摘要： Embodiments of an ultra-stable frequency reference generating system and methods for generating an ultra-stable frequency reference using a two-photon Rubidium transition are generally described herein. In some embodiments, a cavity-stabilized reference laser comprising a laser source is locked to a stabilized cavity. A Rubidium cell is interrogated by a stabilized laser output to cause at least a two-photon Rubidium transition and a detector may detect fluorescence resulting from spontaneous decay of the upper state Rubidium transition. The output of the detector is provided at a wavelength of the fluorescence to lock the cavity-stabilized reference laser to generate a stabilized laser output. A frequency comb stabilizer may be locked to the stabilized laser output to generate a super-continuum of optical wavelengths for use in generating an ultra-stable frequency reference.
