摘要:

部分相干光束对瑞利介质球的辐射力受光束相干性的影响很大。当相干性降低时,作用在聚焦点附近介质球上的辐射力的大小大大降低。对于相干性好的光束,可以利用辐射力来捕获粒子;对于相干性中等的光束,可以利用辐射力来引导和加速粒子。

英文摘要:

The radiation forces on a Rayleigh dielectric sphere induced by a partially coherent light beam are greatly affected by the coherence of the light beam. The magnitude of the radiation forces on a dielectric sphere near the focus point greatly decreases as the coherence decreases. For the light beam with good coherence, the radiation force may be used to trap a particle; and for the light beam with intermediate coherence, the radiation force may be used to guide and accelerate a particle.
