Strong-field index enhancement via selective population of dressed states Academic Article uri icon


  • A three-level [Formula Presented] scheme is proposed in order to achieve a large (resonant) index of refraction with vanishing absorption. This scheme is based on the selective population of one of the dressed states produced by a strong laser field. For modest values of the density and realistic atomic parameters the present scheme gives the index to absorption ratio [Formula Presented] It is to be noted that an off-resonant two-level scheme can also give such a ratio but the index of refraction will be smaller. The present approach to index enhancement is not limited to weak fields, as is the case in some other schemes. © 1997 The American Physical Society.
