Abstract: A compact mid-IR laser device utilizes an external cavity to tune the laser. The external cavity may employ a Littrow or Littman cavity arrangement. In the Littrow cavity arrangement, a filter, such as a grating, is rotated to provide wavelength gain medium selectivity. In the Littman cavity arrangement, a reflector is rotated to provide tuning. A quantum cascade laser gain medium provides 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 for both the output lens and the external cavity 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.

Abstract: 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.
