The Few Cycle SPIDER interferometer system allows complete spectral and temporal characterization of ultrashort optical laser pulses down to 5 fs. It uses a nondrifting, etalon-based interferometer and a material-dispersion stretcher to directly measure spectral phase. It allows simultaneous single-shot detection of amplitude and phase of pulses with spectral bandwidths up to one optical octave.
A new SPIDER instrument for few cycle pulses
With the new FC (Few Cycle) SPIDER APE offers a precision tool for complete spectral and temporal characterization of few electric filed ultra-short optical laser pulses 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 analyzing a spectral interferogram. In combination with a simultaneous measured spectrum, the temporal amplitude and phase are derived in real-time.
This new design enables simultaneous single shot detection of amplitude and phase of pulses with spectral bandwidths up to one optical octave. A high degree of automation for software assisted device calibration and alignment is implemented for user-friendly operation and to enable measurements with low input intensities.
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.
