Abstract: Systems and methods for controlling optical feedback in an optical system. A resonant optical cavity includes at least two cavity mirrors, one of which is a cavity coupling mirror, and has a plurality of optical resonance cavity modes. A radiation source emits a beam of continuous wave radiation and is capable of being scanned whereby a mean optical frequency of the continuous wave radiation beam is adjustable over a range of frequencies, wherein the radiation source is responsive to optical feedback radiation emerging from the cavity, and wherein the mode matching optics couples the beam of continuous wave radiation to the cavity via the cavity coupling mirror. The radiation source and the mode matching optics are aligned so that a mode fill ratio is reduced relative to a maximum mode fill ratio, wherein the laser beam is coupled with a fundamental cavity mode.

Abstract: Systems and methods for characterizing biological specimens, which may involve identifying a cell type or state corresponding to a disease or health condition of a subject. A biological specimen is subjected to electromagnetic radiation for spectroscopic analysis such as Surface Enhanced Raman Spectroscopy (SERS) to determine the relative abundance of proteins or amino acids in the cells, which is used in a comparison to previously stored relative abundance data of a database to automatically identifies at least one of cell type and/or cell state of the cells (or the disease/health state of the subject with the disease state including the possibility of virus infection, or drug susceptibility of a subject to bacteria or fungus). The method may also be employed with biological entities or cellular structures such as exosomes and even protein or nucleic acid fragments to determine disease states or health states of the subject.

Abstract: Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body has the shape of two end-to-end Y's forming a central segment, two branch segments extending from each end of the central segment, and an extension segment extending from each of the four branch segments, to collectively form four unenclosed cell openings that are each semi-hexagonal in shape. Some embodiments include four reinforcement segments with each one extending into a respective cell opening, four voids with each one extending through respective adjacent branch and extension segments, an underbody gap formed under the central segment for refractory interlinking between cell openings, and/or a single stud-welding stud for the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed semi-hexagonal cell openings of adjacent anchoring devices cooperatively form substantially hexagonal cells.

Abstract: A Brillouin modality can be supplemented by an auxiliary modality, such as an optical imaging modality or a spectroscopy modality. In some embodiments, the auxiliary modality can be used to guide the Brillouin measurement to a desired region of interest, so that acquisition times for the Brillouin measurement can be reduced as compared to interrogating the entire sample. The auxiliary modality may have an acquisition speed faster than that of the Brillouin modality. In some embodiment, the auxiliary modality determines a composition of materials within a voxel in the sample interrogated by the Brillouin modality. Using the information provided by the auxiliary modality, the Brillouin signatures corresponding to the materials within the voxel can be unmixed, thereby providing a more accurate measurement of the sample.
