Abstract

The first demonstration to our knowledge in the spectral range from 300 to 1100 nm is presented for the amplitude modulation characteristics of a two-channel 648-pixel liquid crystal spatial light modulator. The broadest spectral amplitude modulation for UV (380-420 nm) and visible-to-near-IR (500-900 nm) pulses to generate a spectral-shifted pulse pair is experimentally realized. The results show that the liquid crystal spatial light modulator has a potential application for attosecond extreme-UV pulse characterization with the conventional SPIDER algorithm and the capability to shape monocycle optical pulses.

摘要

据我们所知，首次展示了在300至1100纳米光谱范围内两通道648像素液晶空间光调制器的振幅调制特性。通过实验实现了对紫外（380 - 420纳米）和可见光至近红外（500 - 900纳米）脉冲的最宽光谱振幅调制，以生成光谱移位脉冲对。结果表明，该液晶空间光调制器在利用传统SPIDER算法表征阿秒极紫外脉冲以及塑造单周期光脉冲方面具有潜在应用价值。
