It is seen that the behaviors of light pressure forces with even order are similar to the zero order force while that of odd order forces are opposite to the zero order one 力的高階諧波項隨著激光強度的增加而增大,而且偶次高階項的作用與零階項的作用相同,奇次項的作用與此相反。
When the intensity of the laser field is weak , the velocity dependence of the average longitudinal force has the doppler shifted lorenztian resonance . at high intensities , there is a kink and change direction of the light pressure force near the point of zero velocity , the effects of the higher order harmonic light pressure forces become significant 當(dāng)激光場強度比較弱時,作用在原子上的力為洛侖茲型,隨著激光強度的增加,依賴于速度的零階力在零速度附近方向發(fā)生了反轉(zhuǎn),出現(xiàn)了扭結(jié)現(xiàn)象。
Therefore , by exerting controllable atomic array and quantum states , it is possible for physical realization of a quantum computer and the communication of quantum states . it is shown that a negative detuning of the laser field from the atomic resonance will lead to nonzero light pressure forces and reduce velocities along the laser beam axis 研究結(jié)果表明,當(dāng)選擇負失諧時,原子將受到來自激光場的阻滯力,在它的作用下,原子沿激光束方向的運動速度大大減小,溫度降低,表現(xiàn)為冷卻效應(yīng)。
