Abstract

We developed a $1\text{- pixel}$ 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 $260–1100\mathrm{nm}$. A phase modulation capability of $55.8\mathrm{rad}$ at $305\mathrm{nm}$ and $14.0\mathrm{rad}$ at $1000\mathrm{nm}$ is enough to compensate for UV-to-NIR nonlinear chirped pulses. The LC-SLM driving parameters of a period $T=13\mathrm{ms}$ and an applied voltage $V_{\mathrm{DD}}=7.0\mathrm{V}$ were determined. The $648\text{- pixel}$ 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.
