A widely tunable 10-m quantum cascade laser phase-locked to a state-of-the-art mid-infrared reference for precision molecular spectroscopy
Papa Lat Tabara Sow, Sinda Mejri, Sean K. Tokunaga +7
We report the coherent phase-locking of a quantum cascade laser (QCL) at 10-m to the secondary frequency standard of this spectral region, a CO2 laser stabilized on a saturated…

Microwave spectroscopy of Lambda-doublet transitions in the ground state of CH
S. Truppe, R. J. Hendricks, S. K. Tokunaga +2
The Lambda-doublet transitions in CH at 3.3 and 0.7 GHz are unusually sensitive to variations in the fine-structure constant and the electron-to-proton mass ratio. We describe meth…
