Abstract

We fabricated a 648 pixel, two-dimensional spatial light modulator (SLM) with a transmittance of more than 85% in the wavelength region from 260 to 1100 nm . The phase modulation characteristics of the liquid-crystal SLM were clarified. Furthermore, the SLM enabled us to compensate for chirp of 270 fs UV pulses and chirp of 120 fs near-IR pulses so that the former and latter pulse durations, respectively, were shortened to 35 and 25 fs . This suggests that the SLM can be utilized, in the UV to near-IR region, for the generation of monocycle optical pulses, pulse shaping, and other applications.
