ABSTRACT:
In spectroscopic mode, the energy levels of an atom, molecule or surface feature are determined by scanning laser frequencies and/or microwave frequencies. Enhanced radiation in the microwave or optical frequency range is detected and the detected spectra characterize the energy levels. In the analytical mode, the laser and/or microwave frequencies are optimized to detect the presence of an atom, molecule or surface feature.
