    "abstract": "Dicke narrowing is a phenomena that dramatically reduces the Doppler width of\nspectral lines, due to frequent velocity-changing collisions. A similar\nphenomena occurs for electromagnetically induced transparency (EIT) resonances,\nand facilitates ultra-narrow spectral features in room-temperature vapor. We\ndirectly measure the Dicke-like narrowing by studying EIT line-shapes as a\nfunction of the angle between the pump and the probe beams. The measurements\nare in good agreement with an analytic theory with no fit parameters. The\nresults show that Dicke narrowing can increase substantially the tolerance of\nhot-vapor EIT to angular deviations. We demonstrate the importance of this\neffect for applications such as imaging and spatial solitons using a\nsingle-shot imaging experiment, and discuss the implications on the feasibility\nof storing images in atomic vapor.",
