我们实验研究了白色光的光学捕获产生的飞秒脉冲从钛：蓝宝石激光器的零色散波长1030 nm附近的硅酸铅光纤泵浦的超连续谱，然后使用微纤维半锥与最终的尖端直径为75 nm的限制光。由于在输出端的高强度梯度，鲁棒的光学捕获是可能的，如使用100 mW的平均泵浦功率对单个酵母细胞所证明的。
We experimentally investigate white light optical trapping by generating a supercontinuum in a lead silicate fibre pumped by femtosecond pulses from a Ti:Sapphire laser near the zero-dispersion wavelength of 1030 nm, before confining the light using a microfibre half taper with a final tip diameter of 75 nm. Due to the high intensity gradient at the output, robust optical trapping is possible, as demonstrated for individual yeast cells using an average pumping power of 100 mW.
