    Abstract: Frequency registration deviations occurring during a scan of a frequency or wavelength range by a spectroscopic analysis system can be corrected using passive and/or active approaches. A passive approach can include determining and applying mathematical conversions to a recorded field spectrum. An active approach can include modifying one or more operating parameters of the spectroscopic analysis system to reduce frequency registration deviation.

    Abstract: A first contact surface of a semiconductor laser chip can be formed to a first target surface roughness and a second contact surface of a carrier mounting can be formed to a second target surface roughness. A first bond preparation layer comprising a first metal can optionally be applied to the formed first contact surface, and a second bond preparation layer comprising a second metal can optionally be applied to the formed second contact surface. The first contact surface can be contacted with the second contact surface, and a solderless securing process can secure the semiconductor laser chip to the carrier mounting. Related systems, methods, articles of manufacture, and the like are also described.

    Abstract: A first contact surface of a semiconductor laser chip can be formed to a target surface roughness selected to have a maximum peak to valley height that is substantially smaller than a barrier layer thickness. A barrier layer that includes a non-metallic, electrically-conducting compound and that has the barrier layer thickness can be applied to the first contact surface, and the semiconductor laser chip can be soldered to a carrier mounting along the first contact surface using a solder composition by heating the soldering composition to less than a threshold temperature at which dissolution of the barrier layer into the soldering composition occurs. Related systems, methods, articles of manufacture, and the like are also described.

    Abstract: A spectrometer cell can include a spacer, at least one end cap, and at least one mirror with a reflective surface. The end cap can be positioned proximate to a first contact end of the spacer such that the end cap and spacer at least partially enclose an internal volume of the spectrometer cell. The mirror can be secured in place by a mechanical attachment that includes attachment materials that are chemically inert to at least one reactive gas compound. The mechanical attachment can hold an optical axis of the reflective surface in a fixed orientation relative to other components of the spectrometer cell and or a spectrometer device that comprises the spectrometer cell. The mirror can optionally be constructed of a material such as stainless steel, ceramic, or the like. Related methods, articles of manufacture, systems, and the like are described.
