Abstract

The fine particle manipulation using optical radiation force has already been investigated in former research. Based upon that, the manufacturing method of the micro parts made up of some fine particles has been developed. However, when the micro parts consist of a lot of fine particles, the manipulation and assembly procedures become time consuming with low work efficiency because of the one by one operation. To solve this problem, a new arrangement method with a single laser beam was realized and proposed in the study, which is able to conduct the assembly procedures efficiently and practically. In detail, the method is to arrange particles by stopping the scanning of a YAG laser beam for a short interval at some appointed positions along the scanning locus to give out a larger amount of input laser energy so that fine particles can be trapped in priority at those stop positions. Therefore it becomes realizable to trap several fine particles at the appointed locations. Furthermore, if the stop positions of the laser scanning are arranged at the same time, the plural trapped fine particles can be manipulated simultaneously. This idea has also been experimentally realized.
