Abstract: An imaging microscope (12) for generating an image of a sample (10) comprises a beam source (14) that emits a temporally coherent illumination beam (20), the illumination beam (20) including a plurality of rays that are directed at the sample (10); an image sensor (18) that converts an optical image into an array of electronic signals; and an imaging lens assembly (16) that receives rays from the beam source (14) that are transmitted through the sample (10) and forms an image on the image sensor (18). The imaging lens assembly (16) can further receive rays from the beam source (14) that are reflected off of the sample (10) and form a second image on the image sensor (18). The imaging lens assembly (16) receives the rays from the sample (10) and forms the image on the image sensor (18) without splitting and recombining the rays.

Abstract: A sensor system for sensing the presence of methane and sulfur hexafluoride in an area includes (i) a laser assembly including a quantum cascade gain medium that generates a MIR output beam that is directed at the area; and (ii) an imager that captures a thermal image of the area when the MIR output beam is generated. To sense the presence of methane, the MIR output beam has a center wavelength that is in the range of between approximately 7.654 and 7.668 microns. Alternatively, to sense the presence of sulfur hexafluoride, the MIR output beam has a center wavelength that is in the range of between approximately 10.56 and 10.58 microns.

Abstract: A device controller (16) for directing a drive current (12A) to a device (12) includes a current driven power source (40) that is electrically connected to the device (12); and a current adjuster (22) electrically connected to the power source (40) in parallel to the device (12). The current adjuster (22) selectively adjusts the drive current (12A) directed to the device (12). For a laser (12), the current adjuster (22) can adjust the drive current (12A) to modulate a center wavelength of an illumination beam (20) generated by the laser (12).

Abstract: A highly portable, high-powered infrared laser source is produced by intermittent operation of a quantum cascade laser power regulated to a predetermined operating range that permits passive cooling. The regulation process may boost battery voltage allowing the use of a more compact, low-voltage batteries.

Abstract: A laser source assembly for providing an assembly output beam includes a first MIR laser source, a second MIR laser source, and a beam combiner. The first MIR laser source emits a first MIR beam that is in the MIR range and the second MIR laser source emits a second MIR beam that is in the MIR range. Further, the beam combiner spatially combines the first MIR beam and the second MIR beam to provide the assembly output beam. With this design, a plurality MIR laser sources can be packaged in a portable, common module, each of the MIR laser sources generates a narrow linewidth, accurately settable MIR beam, and the MIR beams are combined to create a multiple watt assembly output beam having the desired power.
