| Research Abstract |
In a gaseous Bose-Einstein condensate (BEC) of atoms, nonlinear wave propagation such as a soliton and/or an irrotational current like a quantized vortex can be excited. For experimental studies for their characteristics, we aim to form a BEC in the shape of a ring, that is to say an atom wave circuit, instead of a conventional BEC in the shape of a cigar. In this research project, we developed a laser system for transforming the latter BEC into the former one with optical dipole force. In addition, for imprinting an artificial phase distribution in a BEC by the stimulated Raman transition, we made the frequency-stabilized laser source (the wavelength of 780 nm and the frequency width of 22 kHz) and the phase manipulating system for the wavefront of the laser beam.
