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.

Abstract: The present invention provides an apparatus for passively stabilizing the optical pathlength in tunable lasers. Lasers stabilized using the passive stabilization apparatus exhibit reduced mode hop and increased wavelength stability during temperature variations of the laser or surrounding environment. The stabilization makes the laser suitable for a broad range of applications including: optical signal generators and optical multimeters.
