We developed LCOS-SLM as a spatial light modulator for precise pure phase control. Generation of stable multiple spot patterns (MSPs) is important in laser processing, microscopy. We proposed flicker noise reduction method of the MSPs which generated by the LCOS-SLM and confirmed reduction of noise from 2% to 0.5%.
