【 摘 要 】

We demonstrate pulse shaping via arbitrary phase modulation with a reflective, I x 4096 element, liquid crystal spatial light modulator (SLM). The unique construction of this device provides a very high efficiency when the device is used for phase modulation only in a prism based pulse shaper, namely 85%,,. We also present a single shot characterization of the SLM in the spatial domain and a single shot characterization of the pulse shaper in the spectral domain. These characterization methods provide a detailed picture of how the SLM modifies the spectral phase of an ultrashort pulse. (c) 2007 Elsevier B.V. All rights reserved.
