Abstract
  • Recently, we have demonstrated that the \"intrinsic\" linewidth of Quantum Cascade Lasers (QCLs) can go beyond the radiative lifetime of the upper level. This represents the first demonstration of a sub-radiative linewidth for any laser. The intrinsic linewidth of a QCL can be as narrow as hundreds Hz, paving new ways for ultra-sensitive and precise harnessing and detection of molecules. We are working towards full exploitation of such intrinsic properties by designing appropriate phase-lock loops and enhancement-cavities for interaction with molecules. Combination with optical-frequency-comb-synthesizers and appropriate spectroscopic techniques, like saturated-cavity-ring-down-SCAR or polarization spectroscopy can provide unprecedented sensitivity and frequency accuracy for molecular detection.
