FC Spider

FC Spider

The new FC SPIDER (Few Cycle SPIDER) from APE offers a precision tool for complete spectral and temporal characterisation in the red and NIR spectral region of ultra-short optical laser pulses with FWHM down to 5 femtoseconds.

Based on the proven and patented SPIDER technology using a non-drifting, etalon based interferometer and a material-dispersion stretcher, the FC SPIDER directly measures the spectral phase by analysing a spectral interferogram. In combination with a simultaneously measured spectrum, the temporal amplitude and phase are derived in real-time.

The FC SPIDER is the ideal tool to align and monitor the performance of broadband Ti:Sapphire oscillators and amplifier chains with bandwidths starting at 35 nm and supplements the APE SPIDER line towards faster pulses. NEW: Now available is the FC-Spider-VIS, extending spectral coverage down to 400nm.
