Abstract
The purpose of this study to accomplish three-dimensional trapping of micro objects by a YAG laser with the Liquid Crystal Spatial Light Modulator (LCSLM). This paper describes a prototype experimental system. The experimental result shows that performance of phase modulation decreases with the increases of temperature of LCSLM. For this reason, the cooling system is necessary for LCSLM. The experimental result using cooling system shows a constant performance of phase modulation for a LCSLM. Using the cooled LCSLM, we have carried out the two-dimensional trapping of a particle. Using YAG laser a global trapping system has been developed by cooled LCSLM.
