We have used a commercially available liquid-crystal spatial light modulator within a reflective optics pulse-shaping apparatus to shape ultrashort pulses with temporal resolution approaching 10 fs. Using the spatial light modulator as a phase modulator, we produce a variety of complex ultrafast waveforms, including odd pulses, high repetition rate (.23 THz) pulse trains, and asymmetric pulse t...

Spatial light modulators (SLMs) are devices for modulating amplitude, phase, or polarization of beams on demand. Such regarded as the backbone optical information parallel processing and future computers. Currently, SLMs mainly operated in an electrical addressing manner, wherein modulated by signals. However, all-optical systems prefer to control directly (i.e., optically addressed, OA) withou...
