【摘要】 本文从理论角度论证了飞秒激光作为光镊光源的可行性,给出了飞秒激光作用时微粒所受力理论计算公式,并在此基础上给出了对应于不同参数的光镊稳定性图形。我们还进一步分析了飞秒激光作为光镊光源相对于其他激光的特有性质。更多还原

【Abstract】 We have theoretically demonstrated the feasibility of the femtosecond laser as a source for optical tweezers. Looking upon the femtosecond laser pulse as a sampling of the CW laser, we presented the formulae of force of the femtosecond laser pulses exerted on the micrometer-sized particle in solution. Furthermore, for femtosecond laser tweezers we have calculated the dependence of trap stability on variable parameters. We also analysed the unique character of the femtosecond laser tweezers comparing with other source.更多还原
