We developed a ultraviolet-to-near-infrared (UV-to-NIR) liquid-crystal spatial light modulator (LC-SLM) and clarified its phase modulation properties in detail, for the first time to our knowledge. The employed liquid crystal is transparent over . A phase modulation capability of at and at is enough to compensate for UV-to-NIR nonlinear chirped pulses. The LC-SLM driving parameters of a period and an applied voltage were determined. The extension of this new device will permit us to realize the high-power generation of single subcycle optical pulses and the direct UV-to-NIR pulse shaping.
