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 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.

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 tunable light source (10) that generates a source beam (12) having a tunable source frequency (12a) includes an emitter assembly (14), a first frequency generator (16), and a first filter (18). The emitter assembly (14) emits an emitter beam (14a), and the first frequency generator (16) receives the emitter beam (14a) and generates a plurality of first frequency lines (16b). The first filter (18) filters the first frequency lines (16b) to transmit a first filter beam (18a) that includes only one of the first frequency lines (16b). The light source (10) can include a second frequency generator (20) that converts the first filter beam (18a) into a plurality of second frequency lines (20b), and a second filter (22) that filters the second frequency lines (20b) to provide a second filter beam (22a) having the source frequency (12a).
