Efficient Nonlinear Frequency Conversion with Maximal Atomic Coherence.

چکیده
We demonstrate efficient nonlinear frequency conversion in atomic Pb vapor under conditions where the linear susceptibility and the effective nonlinear susceptibility are of the same order. This is accomplished by using electromagnetically induced transparency to prepare a near-maximal atomic coherence on a Raman transition. This strongly driven transition is used to convert an intense laser beam from 425 to 293 nm with an efficiency of ,40%. [S0031-9007(96)01644-4]

Quantum manipulation of two-color stationary light: Quantum wavelength conversion
We present a quantum manipulation of a traveling light pulse using double atomic coherence for two-color stationary light and quantum frequency conversion. The quantum frequency conversion rate of the traveling light achieved by the two-color stationary light phenomenon is near unity. We theoretically discuss the two-color stationary light for the frequency conversion process in terms of pulse ...
متن کاملAdiabatic frequency conversion of ultrafast pulses
A new method for efficient, broadband sum and difference frequency generation of ultrafast pulses is demonstrated. The principles of the method follow from an analogy between frequency conversion and coherent optical excitation of a two-level system. For conversion of ultrafast pulses, the concepts of adiabatic conversion are developed further in order to account for dispersion and group veloci...

LLE Review, Volume 74 125 In the interaction of strong fields with matter, considerable interest has been shown in the development of high-efficiency frequency up-conversion of ultrashort laser pulses. One important area of interest is in ultrafast laser–solid interactions where up-conversion can lead to higher absorption due to higher-density interactions1 and to an enhancement of the pulse-in...
متن کاملEfficient two-process frequency conversion through a dark intermediate state
Two simultaneous three wave mixing processes are analyzed, where an input frequency is converted to an output frequency via an intermediate stage. By employing simultaneous phase-matching and an adiabatic modulation of the nonlinear coupling strengths, the intermediate frequency is kept dark throughout the interaction while obtaining high conversion efficiency. This feat is accomplished in a ma...
متن کاملFully efficient adiabatic frequency conversion of broadband Ti:sapphire oscillator pulses.
By adiabatic difference-frequency generation in an aperiodically poled nonlinear crystal-a nonlinear optical analog of rapid adiabatic passage in a two-level atomic system-we demonstrate the conversion of a 110 nm band from an octave-spanning Ti:sapphire oscillator to the infrared, spanning 1550 to 2450 nm, with near-100% internal conversion efficiency. The experiment proves the principle of co...
