摘　　要：通过光束来实现对物体的吸引一直是人们的梦想。近年来,对牵引光束的研究引起了人们极大的兴趣,而光吸引的理论证实则使得这种研究兴趣达到高峰。通过设计并调节牵引光束以及被操控微粒的参数,可以实现通过光力对微粒的逆光吸引。目前,人们提出了多种牵引光束,并在实验中得到了证实。随着进一步研究,牵引光束将为基础和应用研究提供更多的机会,走出实验室,最终走向消费市场。The idea of using optical beams to attract objects has been a dream of people for long time.The study of optical tractor beams has initiated great interests recently,and the theoretical demonstration of optical pulling force invoked the climax.By designing and tuning the parameters of optical tractor beams and small particles,micro-particles can be pulled towards the source by using optical forces.A great variety of optical tractor beams were proposed and demonstrated in experiments.The next generation of optical tractor beams will offer new opportunities for fundamental and applied research,and finally been used in consumer market.
