GENERATION OF HIGH-FIDELITY PROGRAMMABLE ULTRAFAST OPTICAL WAVE-FORMS

We report advances in the generation of ultrafast optical waveforms wi th programmable time-dependent amplitude and temporal phase profiles. Two liquid-crystal spatial light modulators are employed in a novel ar rangement to permit the generation of programmable ultrashort waveform s with exceptional versatility and fidelity. We also demonstrate ultra fast waveform generation in which the time-dependent polarization prof ile is controlled.
