Zhao et al., Frequency stabilization of a quantum cascade laser by weak resonant feedback from a Fabry-Perot cavity, Optics Letters. Frequency-stabilized mid-infrared lasers are valuable tools for precision molecular spectroscopy. However, their implementation remains limited by complicated stabilization schemes. Here we achieve optical self-locking of a quantum cascade laser to the resonant leak-out field of a highly mode-matched two-mirror cavity. The result is a simple approach to achieving ultra-pure frequencies from high-powered mid-infrared lasers. For short time scales (<0.1 ms), we report a linewidth reduction factor of 3\u00d710^(-6) to a linewidth of 12 Hz. Furthermore, we demonstrate two-photon cavity-enhanced absorption spectroscopy of an N2O overtone transition near a wavelength of 4.53 um.", "distribution": [{"accessURL": "https://doi.org/10.18434/mds2-2409", "title": "DOI Access for Frequency stabilization of a quantum cascade laser by weak resonant feedback from a Fabry-Perot cavity"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig1_data.xls", "format": ".xls", "mediaType": "application/vnd.ms-excel", "title": "Fig. 1:  Conceptualization and model for a quantum cascade laser coupled to a Fabry-Perot cavity by weak optical feedback."}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig1_data.xls.sha256", "mediaType": "text/plain", "title": "SHA256 File for Fig. 1:  Conceptualization and model for a quantum cascade laser coupled to a Fabry-Perot cavity by weak optical feedback."}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig4_data.xls", "format": ".csv", "mediaType": "application/vnd.ms-excel", "title": "Fig. 4:  QCL line width analysis - power spectral densities"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig4_data.xls.sha256", "mediaType": "text/plain", "title": "SHA256 File for Fig. 4:  QCL line width analysis - power spectral densities"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig5_data.xls", "format": ".csv", "mediaType": "application/vnd.ms-excel", "title": "Fig. 5:  Two-photon absorption spectroscopy of N2O in the mid-infrared"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/Fleisher_stableQCL_rev1_fig5_data.xls.sha256", "mediaType": "text/plain", "title": "SHA256 File for Fig. 5:  Two-photon absorption spectroscopy of N2O in the mid-infrared"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/readme.txt", "format": ".txt", "mediaType": "text/plain", "title": "Read me file"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2409/readme.txt.sha256", "mediaType": "text/plain", "title": "SHA256 File for Read me file"}], "identifier": "ark:/88434/mds2-2409", "issued": "2021-05-20", "keyword": ["Environment and Climate", "diode lasers", "greenhouse gases", "laser metrology", "laser stabilization", "marine mammals", "nitrous oxide", "oceans", "optical resonators", "ph", "quantum cascade lasers", "remote sensing", "seabirds", "two-photon absorption"], "landingPage": "https://data.nist.gov/od/id/mds2-2409", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2021-05-18 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://doi.org/10.1364/OL.427083"], "theme": ["Chemistry:Analytical chemistry", "Environment:Greenhouse gas measurements", "Metrology:Optical, photometry, and laser metrology", "Physics:Spectroscopy"], "title": "Frequency stabilization of a quantum cascade laser by weak resonant feedback from a Fabry-Perot cavity"}
