Electromagnetically induced transparency in Doppler-broadened three-level systems with resonant standing wave drive

subject

description

Summary form only given. Electromagnetically induced transparency (EIT) and related phenomena such as lasing without inversion (LWI) are topics of increasing interest in quantum optics. In EIT, an otherwise absorbing medium is made transparent to a weak coherent field on resonance with a certain atomic transition by applying an intense coherent "driving" field to an adjacent transition. There has been a large number of theoretical papers and EIT was demonstrated experimentally. Up to now, most theoretical papers dealing with EIT in gas media have considered only the case of a traveling (TW) driving field. In contrast, we study EIT in Doppler broadened three-level media with standing wave (SW) driving and focus our analysis into the advantages of using a SW driving configuration instead of a TW one when the frequency of the probe field is larger than that of the driving field, i.e., the so-called frequency up-conversion regime.
