The FC-SPIDER (Few-Cycle SPIDER) by APE provides spectral and temporal characterization of ultrashort laser pulses down to below 5 fs. It covers the visible, the near-infrared as wellas the infrared spectral region. This high-precision tool is ideal for aligning and monitoring the performance of broadband Ti:Sa oscillators and amplifier chains.
Based on the proven and patented Spider (Spectral Phase Interferometry for Direct Electric-field Reconstruction) technology, using a non-drifting, etalon interferometer and a material dispersion stretcher, the FC Spider directly measures the spectral phase by analyzing a spectral interferogram. In combination with a simultaneously measured power spectrum, real-time calculation and visualization of the spectral and temporal amplitude and phase is accomplished.
