Optical Parametric Amplification with Periodically Poled KTiOPO4
This thesis explores the use of engineered nonlinear crystals from the KTiOPO4 (KTP) family as the gain material in optical parametric amplifiers (OPAs), with the aim to achieve more knowledge about the benefits and limitations of these devices. The work aims further at extending the possible applications of OPAs by constructing and investigating several efficient and well performing amplifiers...
متن کاملControlled transport of matter waves in two-dimensional optical lattices.
We propose a method for achieving dynamically controllable transport of highly mobile matter-wave solitons in a driven two-dimensional optical lattice. Our numerical analysis based on the mean-field model and the theory based on the time-averaging approach demonstrate that a fast time-periodic rocking of the two-dimensional optical lattice enables efficient stabilization and manipulation of spa...
متن کاملInstability-induced localization of matter waves in moving optical lattices
By using a one-dimensional nonpolynomial nonlinear mean-field model, we numerically analyze the process of the loading of the Bose-Einstein condensate into a moving one-dimensional optical lattice. We demonstrate that the recently observed dynamical instability of the Bloch states of a repulsive condensate in a moving optical lattice can lead to formation of trains of spatially localized wave p...
متن کاملTheory of Nonlinear Matter Waves in Optical Lattices
Received (received date) Revised (revised date) We consider several effects of the matter wave dynamics which can be observed in Bose-Einstein condensates embedded into optical lattices. For low-density condensates we derive approximate evolution equations, the form of which depends on relation among the main spatial scales of the system. Reduction of the Gross-Pitaevskii equation to a lattice ...
متن کاملControlled transport of matter waves in driven optical lattices
The idea of controlled manipulation of stable, spatially localized matter-wavepackets is attractive from the point of view of the developing atomic interferometry and precise measurement techniques based on the use of the Bose-Einstein condensates (BECs). In the recent years optical lattices were suggested as a means of achieving controlled transport of matter waves. In particular, theoretical ...
