Inspired by a theory previously derived by Wolf and Collett [Opt. Commun. 25, 293 (1978)], we demonstrate that partially coherent Gaussian-Schell model fluctuating sources (GSMS) produce exactly the same optical forces as a fully coherent laser beam. We also show that this kind of source helps to control the magnitude of the light-matter mechanical interaction in biological samples, which are sensitive to thermal heating induced by higher intensities. The latter is a consequence of the fact that the same photonic force can be obtained with a low-intensity GSMS as with a high-intensity laser beam.
受 Wolf 和 Collett 此前提出的理论启发[Opt. Commun. 25, 293 (1978)]，我们证明部分相干高斯-谢尔模型脉动光源（GSMS）产生的光力与完全相干激光束完全相同。我们还表明，这种光源有助于控制生物样本中光物质机械相互作用的大小，因为生物样本对高强度引起的热加热很敏感。这是因为可以用低强度 GSMS 获得与高强度激光束相同的光子力。
