Abstract: A polarimeter for measuring chirality of a material comprising an optical ring cavity comprising a plurality of reflective elements configured to promote bi-directional propagation of a laser beam within the cavity, a laser-emitting device configured to introduce a first input laser beam and a second input laser beam into the ring cavity, and a Faraday rotator and a phase compensator configured to suppress a birefringent background as the first and second laser beams pass through the ring cavity, wherein the plurality of mirrors, Faraday rotator, and phase compensator are configured such that light from the first and second laser beams passes through a chiral material located within the cavity a sufficient number of times for a measurement of optical rotary dispersion (ORD) and circular dichroism (CD) of light transmitted through the chiral material to be obtained. Particular implementations include monolithic ring cavities or microresonators or use of intra-cavity gain media.

Abstract: A method and system for producing a neutral beam of spin polarized Hydrogen isotopes by photodissociating compound molecules are provided. Each compound molecule comprises a Hydrogen isotope and a second element. A molecular beam is generated by passing the compound molecules through a nozzle. The molecular beam is introduced into a photodissociation chamber. The molecular beam is photodissociated into spin polarized Hydrogen isotopes and second elements by intersecting the molecular beam with a circularly polarized photolysis laser beam. The spin polarized Hydrogen isotopes are guided, accelerated, and neutralized.

Abstract: A resonant optical cavity ellipsometer system is provided. The system can be used to conduct time-dependent arid sensitive measurement of ellipsometric parameters of matter. In a particular use, the system can provide time resolution abetter than 1 microsecond. In a particular implementation, matter can be probed within the evanescent wave generated by intra-cavity total reflection.
