We demonstrate fast response time in working LCOS SLMs for the visible wavelength range applications. The same LCOS SLM can be modulated for phase-only applications and amplitude applications separately. For phase-only applications, the LCOS can achieve more than 2π of phase depth modulation at 640 nm wavelength. Sub-millisecond response time with no degradation of the contrast ratio or diffraction efficiency is demonstrated.
