Femtosecond laser filamentation is generally initialized from unpredictable symmetry breaking caused by random noise, causing it to be barely controlled. However, it is always anticipated for stable and controllable filamentation. We present and demonstrate the idea that hybridly polarized vector fields with axial symmetry broken polarization, associated with a pair of orthogonally linearly polarized vortices carrying the opposite-handed orbital angular momenta, could achieve controllable and robust multiple filamentation. Here, our motivation is to unveil the underlying physics behind such controllable and robust multiple filamentation. The symmetry breaking should first be actively controllable and then be able to effectively inhibit random noise. Robust multiple filamentation is inseparable from the fact that the phases between the multiple filaments are always locked. In contrast, uncontrollable multiple filamentation is always accompanied with loss of phase, i.e., the multiple filaments become incoherent to each other. Our results may offer a suggestion for achieving controllable and robust multiple filamentation in other systems.and Equipment Development Project (2012YQ17004); Collaborative Innovation Center of Extreme Optics.

为定量描述柱透镜参数对三维成像过程中荧光分子轴向定位精度的影响,本文研究了柱透镜参数与点扩散函数椭圆率的相互关系.基于Olympus IX-83倒置荧光显微镜搭建成像系统,利用3个不同焦距柱透镜进行实验,通过柱透镜标定曲线的线性变化范围及该范围内曲线的斜率分析柱透镜参数选择上的优劣,优化并提高轴向定位的精度和深度.选择合适的柱透镜参数可实现标定曲线在焦平面上下1 μm范围线性变化,轴向定位精度为16 nm,并采用优化的标定曲线对肌动蛋白微丝进行三维超分辨成像.
