    摘要: A laser source assembly (210) for generating an assembly output beam (212) includes a first laser source (218A), a second laser source (218B), and a dispersive beam combiner (222). The first laser source (218A) emits a first beam (220A) having a first center wavelength, and the second laser source (218B) emits a second beam (220B) having a second center wavelength that is different than the first center wavelength. The dispersive beam combiner (222) includes a common area 224 that combines the first beam (220A) and the second beam (220B) to provide the assembly output beam (212). The first beam (220A) impinges on the common area (224) at a first beam angle (226A), and the second beam (220B) impinges on the common area (224) at a second beam angle (226B) that is different than the first beam angle (226A). Further, the beams (220A) (220B) that exit from the dispersive beam combiner (222) are substantially coaxial, are fully overlapping, and are co-propagating.

    摘要: A compact mid-IR laser device utilizes a quantum cascade laser to provide mid-IR frequencies suitable for use in molecular detection by signature absorption spectra. The compact nature of the device is obtained owing to an efficient heat transfer structure, the use of a small diameter aspheric lens and a monolithic assembly structure to hold the optical elements in a fixed position relative to one another. The compact housing size may be approximately 20 cm×20 cm×20 cm or less. Efficient heat transfer is achieved using a thermoelectric cooler TEC combined with a high thermal conductivity heat spreader onto which the quantum cascade laser is thermally coupled. The heat spreader not only serves to dissipate heat and conduct same to the TEC, but also serves as an optical platform to secure the optical elements within the housing in a fixed relationship relative on one another. A small diameter aspheric lens may have a diameter of 10 mm or less and is positioned to provided a collimated beam output from the quantum cascade laser. The housing is hermetically sealed to provide a rugged, light weight portable MIR laser source.

In this embodiment, the MIR beams (356A) (356B) are directed at the combiner lens (364) and the combiner lens (364) focuses the MIR beams (356A) (356B) onto a fiber facet (366A) of the output optical fiber (366). Moreover, the output optical fiber (366) can include an AR coating (366B) on the fiber facet (366A).

    摘要: A lens may operate in the mid-IR spectral region and couple highly divergent beams into highly collimated beams. In combination with a light source having a characteristic output beam, the lens may provide highly stable, miniaturized mid-IR sources that deliver optical beams. An advanced mounting system may provide long term sturdy mechanical coupling and alignment to reduce operator maintenance. In addition, devices may also support electrical and thermal subsystems that are delivered via these mounting systems. A mid-IR singlet lens having a numerical aperture greater than about 0.7 and a focal length less than 10 mm may be combined with a quantum well stack semiconductor based light source such that the emission facet of the semiconductor lies in the focus of the lens less than 2 mm away from the lens surface. Together, these systems may provide a package that is highly portable and robust, and easily integrated with external optical systems.

    摘要: Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section, a motion section, and an actuator. The base section includes a proximal and distal portion, and the laser and the dispersive element mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member positioned at the proximal portion and the reflector positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member. The actuator is in selectively engagable abutment against the distal portion of the motion section to move the reflector with respect to the dispersive element about the torsional member to tune the external cavity laser.
