    Abstract: A laser (14) includes an optical amplifier array system (17) that generates a plurality of laser beams (24); and a beam combiner (18) that coherently combines the plurality of laser beams (24) to form a combination beam (26) having a hollow center in a near field. The combination beam (26) with the hollow center allows for the use of a beam director (19) having an on-axis, reflective beam expander (21) without (i) loss in power, (ii) degradation of beam quality, or (iii) excessive heating of the beam expander (21).

    Abstract: A spectral imaging device (1312) for capturing one or more, two-dimensional, spectral images (1313A) of a sample (1310) including (i) an image sensor (1328), (ii) an illumination source (1314), (iii) a beam path adjuster (1362), and (iv) a control system (1330). The illumination source (1314) that generates an illumination beam (1316) that is directed along an incident sample beam path (1360) at the sample (1310). The beam path adjuster (1362) selectively adjusts the incident sample beam path (1360). The control system (1330) controls (i) the illumination source (1314) to generate the illumination beam during the first capture time, (ii) the image sensor (1328) during the first capture time to capture first information for the first spectral image (1313A), and (iii) the beam path adjuster (1362) to selectively adjust the incident sample beam path (1360) relative to the sample (1310) during the first capture time while the image sensor (1328) is accumulating the information for the first spectral image (1313A).

    Abstract: A laser assembly (10) for generating a pulsed output beam (16) includes a quantum cascade device (12); and a laser driver (14A) that controls the voltage to the quantum cascade device (12) in a pulsed drive profile (950) to generate the pulsed output beam (16). The pulsed drive profile (950) includes a plurality of spaced on-time segments (952) in which the laser driver (14A) directs voltage to the quantum cascade device (12), and at least one off-time segment (954) in which the laser driver (14A) pulls down the voltage from the quantum cascade device (12). The off-time segment (954) occurs between two on-time segments (952).

    Abstract: A flow cell assembly (16) for a fluid analyzer (14) that analyzes a sample (12) includes (i) a base (350) that includes a base window (350B); (ii) a cap (352) having a cap window (352B) that is spaced apart from the base window (350B); and (iii) a gasket (360) that is secured to and positioned between the base (350) and the cap (352), the gasket (360) having a gasket body (360A) that includes a gasket opening (360B). The gasket body (360A), the base (350) and the cap (352) cooperate to define a flow cell chamber (362). Moreover, an inlet passageway (366) extends into the flow cell chamber (362) to direct the sample (12) into the flow cell chamber (362); and an outlet passageway (368) extends into the flow cell chamber (362) to allow the sample (12) to exit the flow cell chamber (362).
