Our study shows that the optical potential of the diffracted light of the semi - gaussian beam is far higher than that of the evanescent - light wave, and its maximum normal velocity of the incident atoms can be far grater than that of the evanescent - light wave under the same parameters, so the blue - detuned semi - gaussian beam, as a novel atomic mirror, can be used to efficiently reflect atoms with a normal velocity of greater than 1 m / s
研究表明，半束蘭失諧高斯光束衍射光場的光學勢遠大於消逝波光場的光學勢，在同樣的參數條件下，入射原子的最大速度也比消逝波光場的大，所以作為一種新穎的原子反射鏡，半束蘭失諧高斯光束可以被用來有效的法向速度大於1m s的入射原子。 -

On the basis of theories of physics, geometrical optics and photometry, the optical properties of collimated light beam incident upon single fiber perpendicular to the fiber axis are studied. by exploring the behaviors of reflected light and transmitted light from single fiber, the distribution of the light is described and the proportionalities between the intensity of the reflected, transmitted and scatered light are obtained respectively, and the different laws governing the intensity of diffused light and transmitted light from single fiber between near and far field are discussed. experiments demonstrate that the decrease of projecting light in far field is in direct proportion for the increase of fiber diameter, which serves as the theoretical basis for a series optics equations, as well as for the designment for photoelectric deviccs for detecting fibers

However, the intensity gradient ( force ) of the diffracted light of the semi - gaussian beam is far smaller than that of the evanescent - light wave, so its spontaneous emission probability is greater than that from the evanescent - light one when the normal velo city of the incident atom is greater
然而，因為半束蘭失諧高斯光束衍射光場的強度梯度力遠小於消逝波光場，所以當入射原子速度較大時，原子在半束蘭失諧高斯光束衍射光場中的自發輻射幾率要大於消逝波光場。 -
In photorefractive crystal light illumination changes the refractive index of the crystal due to linear electrooptical effect, which in turn changes the light distribution. as a result of the development of this process, a beam, called the phase conjugation wave, leaves the crystal back along the direction of the incident beam and is its phase conjugate replica
