  • Patent number: 10852620
    Abstract: In example embodiments, a radiation source uses Rydberg states to generate coherent THz radiation (e.g., in the range of 1-20 THz). The radiation source includes a pair of pump lasers (e.g., external-cavity diode lasers (ECDLs)) optically coupled (e.g., by a dichroic mirror and optical fiber) to a heated vapor cell (e.g., a vacuum chamber) holding an atomic species (e.g., rubidium (Rb)). The pump lasers optically pump the atomic species (e.g., Rb) to a predetermined Rydberg state (e.g., the nD5/2 state), which creates a population inversion between that state (e.g., the nD5/2 state) and a lower lying Rydberg state (e.g., the (n+1)P3/2 state). The emission between these two strongly dipole coupled Rydberg states generates coherent THz radiation.
