When the laser frequency is larger than the atomic resonance frequency ( blue detuning ), the atoms will experience a repulsing force that will repulse the atoms to the minimum place of light field. this is the principle of atomic mirror or atomic guide and trap. in this thesis, we propose three novel mirrors to reflect atoms by using intensity gradient induced by a blue - detuned semi - gaussian laser beam, a blue - detuned semi - ellipse - gaussian laser beam and a blue - detuned semi - flattened - gaussian laser beam
