message: Anybody know much about the current applications of EIT? Using the googly I was able to find a paper  by HP labs doing some interesting stuff. Anything else?---One Son of Ole 06:02, 23 January 2007 (UTC)
replies: text: I have a doubt that EIT effect was first proposed in 1990. McCall had a paper in 1969 proposing self induced transparancy effect via carefully constructed indicident field. The later research has shown that any signal whose dynamics is faster than dephasing time will lead to SIT effect at sufficient amplitude. I am not sure pioneers listed in this Wiki page are correct. 86.19.244.178 (talk) 16:58, 8 November 2023 (UTC)
replies: text: these are actually two quite different effects: self-induced transparency is seen for short, strong pulses interacting with an ensemble of two-level atoms so that absorption and reemission allows the pulse to propagate without losses (cf. ). EIT is a quantum effect seen with a three-level systems (in the simplest case) in which a weak probe field is not absorbed due to the pump moving the atoms to a dark state. There's even a paper discussing how both effects can be realized together . Harris (1990) is cited as the one who first observed in text books like Scully, Quantum Optics or reviews like . --Qcomp (talk) 20:55, 8 November 2023 (UTC)

thread_title: Applications of EIT

message: I recently wrote in my sandbox for a class I am taking and thought, perhaps, the information in it would be useful to expand the connection between EIT and ATS. You can find it here. It describes that these two effects can be separated into intensity regimes, at least in certain configurations, with regards to the coupling laser. Hope it ends up being helpful!
I have posted a similar note about this in the ATS talk, since it pertains to that as well.  — Preceding unsigned comment added by Inaginni (talk • contribs) 21:39, 28 January 2016 (UTC)
