论文摘要
模拟实时场景以预测连续波（CW）以及飞秒脉冲激光器的光学诱捕行为是一个挑战性的问题。尤其是这样，因为对于紧密聚焦的激光，还必须包括光学KERR效应以及热非线性。我们在这里显示了CW和飞秒脉冲激光介导的光学捕获之间在瑞利式中的散射和梯度力中的效果。在我们新开发的模型中，在实际光学诱捕方案中预测陷阱的稳定性以及提供有关溶剂，探针和光学参数（如激光类型，功率范围，波长等）的信息也将更加容易。
Simulating real-time scenarios to predict optical trapping behavior for continuous wave (CW) as well as femtosecond pulsed lasers is a challenging problem. This is especially so, because, for a tightly focused laser, one must also include optical Kerr effect as well as thermal nonlinearity. We show here the distinct differences between CW and femtosecond pulsed laser mediated optical trapping via their effect in scattering and gradient forces in the Rayleigh regime. In our newly developed model, it will also be easier to predict the stability of the trap in real optical trapping scenario as well as provide information regarding choice of solvents, probes, and optical parameters like laser type, power range, wavelength, etc. as may the cases be.
