Phys. Rev. A 65, 023806 (2002) [5 pages]Width of the electromagnetically induced transparency resonance in atomic vaporReceived 11 June 2001; published 4 January 2002 The width of the electromagnetically induced transparency resonance is studied in rubidium vapor. Nonlinear dependence of the width on drive intensity that is caused by Doppler broadening and optical pumping is found. Density-matrix analysis supports the observed dependence. The discrepancies between experimental data and theoretical prediction are discussed. © 2002 The American Physical Society URL:
