Laser frequency offset locking using electromagnetically induced transparency
The authors have used an electromagnetically induced transparency resonance in rubidium as a dispersive reference to lock the relative frequency of two lasers to the atomic ground-statehyperfine splitting. The beat frequency between the two lasers directly generates a microwave signal at 3.036GHz (⁸⁵Rb) or 6.835GHz (⁸⁷Rb). High bandwidth (600kHz) feedback was achieved with only low-frequency (10MHz)electronics using the frequency modulation sideband method. The spectral width of the microwave...[Show more]
