    "abstract": "We report an experimental study of an all-optical three-photon-absorption\nresonance (known as a \"N-resonance\") and discuss its potential application as\nan alternative to atomic clocks based on coherent population trapping (CPT). We\npresent measurements of the N-resonance contrast, width and light-shift for the\nD1 line of 87Rb with varying buffer gases, and find good agreement with an\nanalytical model of this novel resonance. The results suggest that N-resonances\nare promising for atomic clock applications.",
