Loading and cooling of cesium atoms in 3D optical lattice;

The ground state energy and the average atom number per lattice site of 7Li atoms that are loaded into an optical lattice have been calculated when the repulsive three-body interaction is considered.

We study the quantum phases that may arise when 7Li atoms that possess an attractive two-body interaction are loaded into an optical lattice.

The recent development of lattice atom optics is introduced, including atomic optical lattices, atomic magnetic lattices and magneto-optical lattices, and some new results of atomic magnetic lattices and magneto-optical lattices, and some new results on the investigations of magnetic and magneto-optical lattices are reported.

Then optical lattices produced by interfering laser beams are considered.

Quasi-phase-matched crystals(optical superlattices) are a type of artificial nonlinear optical material which has recently attracted much attention on account of its wide application in nonlinear frequency conversion such as second-harmonic generation, third-harmonic generation and optical parametric oscillation.

Combining optical superlattice with all-solid.

We use one aperiodic structure optical superlattice to achieve the output of multi-wavelength second harmonic generation for Ti:sapphire pumping ps-OPA Laser.

Novel spatial gap solitons in photonic lattices;

Novel discrete solitons in light-induced photonic lattices;

In our experiment,we illuminate the area of light induced photorefractive photonic crystal,which the fre- quency of the latter is the same as the frequency of light of forming the photonic crystal,when the angle between incidence light and the direction of the period of photorefractive photonic lattice,is lesser than 12°,we observed the localized phe- nomenon of photorefractive photonic lattice.
