Dependence of enhanced Kerr nonlinearity on coupling power in a three-level atomic system.
نویسندگان
چکیده
We study the enhanced Kerr-nonlinear coefficient in a three-level A-type atomic system for various coupling-beam powers. The Kerr-nonlinear coefficient behaves very differently in the strong and the weak coupling power regions and changes sign when the coupling or probe frequency detuning changes sign. Comparisons of Kerr-nonlinear coefficients as functions of probe frequency detuning, coupling power, and coupling frequency detuning are presented.

Enhanced Kerr nonlinearity via atomic coherence in a three-level atomic system.
We measure the Kerr-nonlinear index of refraction of a three-level Lambda-type atomic system inside an optical ring cavity. The Kerr nonlinearity is modified and greatly enhanced near atomic resonant conditions for both probe and coupling beams. The Kerr nonlinear coefficient n(2) changes sign when the coupling beam frequency detuning switches sign, which can lead to interesting applications in...
متن کاملControlling the cavity field with enhanced Kerr nonlinearity in three-level atoms
We experimentally demonstrate cavity field control by another laser beam with three-level L-type atoms inside an optical ring cavity. By adjusting the frequency detuning of the controlling beam ~coupled to one of the atomic transitions!, the intensity of the cavity field interacting with another atomic transition is switched on and off. Such all-optical switching between two steady states is ca...
متن کاملBistability and instability of three-level atoms inside an optical cavity
Optical bistability and dynamic instability are experimentally observed and studied in a system consisting of three-level L-type rubidium atoms in an optical ring cavity. The bistable behavior and self-pulsing frequency are experimentally manipulated by changing the controlling and cavity field parameters ~power and frequency!. These nonlinear effects are influenced by the enhanced Kerr nonline...
متن کاملControllable Kerr Nonlinearity via Incoherent Pump Fields in Semiconductor Quantum Wells
A theoretical investigation is carried out into the impact of incoherent pumping fields and quantum interference induced by incoherent pumping fields on the Kerr nonlinearity in a three-level asymmetric semiconductor quantum well system. It is found that Kerr nonlinearity is so sensitive to the rate of incoherent pumping fields, but insensitive to the quantum interference induced by incoherent ...
متن کاملControlling light by light with three-level atoms inside an optical cavity.
We present our experimental demonstration of controlling the cavity output intensity of one laser beam with the intensity of another laser beam in a composite system consisting of a collection of three-level ?-type rubidium atoms and an optical ring cavity. When the intensity of the controlling beam is modulated with a square waveform, the cavity output power switches on and off (with a distinc...
