摘要：

Fluorinated polyimide micro-objects having large birefringence of Delta n = -0.13 (refractive index n(1) = 1.62, n(2) = 1.49 for the wavelength lambda = 1.06 mu m), which were fabricated by reactive ion etching and suspended in water (n = 1.33), were trapped and angularly aligned in a single Gaussian laser beam (lambda = 1.06 mu m, power P > 3 mu W). The optically induced angular alignment effect is caused by the transfer of spin angular momentum due to the interaction between their birefringence and the linearly polarized light.
