Research Studies on Electromagnetically Induced Transparency
Abstract
The final report describes progress in the use of electromagnetically induced transparency for the realization of new types of nonlinear interactions and processes. We have worked in two areas: (1) The generation of femtosecond pulses by phased and anti-phased molecular states and the use of this radiation for new types of physical processes, and (2) The demonstration of elementary nonlinear optical processes at low-light-levels. Highlights of the work on this program include the suggestion and first demonstration of the use of an EIT-like Raman process to produce a spectrum with a width over 50,000 cm-1 of bandwidth, and the compression of this radiation to pulses of several femtoseconds in length. By using a technique, which we call multiplicative, we are able to obtain over 200 sidebands. In the future this should allow the synthesis of sub-cycle waveforms of arbitrary shape. In other work under this contract, we have observed an efficient nonlinear optical process at an energy of several pJ.
