Our Spider – Spectral Phase Interferometry for Direct Electric-field Reconstruction – family is designed for phase resolved ultrafast pulse measurements. FC (Few Cycle) Spider offers a precision tool for the complete characterization of ultrashort laser pulses with just a few electric field cycles — sub 5 fs pulse width. For less broadband pulses Spider with grating stretcher is the best choice for pulses between 15 fs and 500 fs at ~ 0.8 µm or 1 µm central wavelength.
Important software features for advanced pulse characterization are provided with all APE Spiders. If desired, a notebook with pre-installed software can be delivered optionally together with the instrument.

Central Wavelength ~ 0.8 µm or 1 µm | 15 - 500 fs (Click here for details) Spider is best suited for the characterization of Lasers with ~ 0.8 µm or 1 µm central wavelengths. It handels pulses with relatively small spectral bandwidths, and therefore longer pulses in the range of about 15 to 500 fs. | Wavelengths for VIS, NIR, IR | < 10 fs Pulses (Click here for details) The precise characterization of very short pulses down to < 5 fs is available with the FC Spider, whereas FC stands for few electric-field cycles. FC Spider is available for different wavelength ranges: VIS, NIR, and IR |
In comparison to FROG, Spider offers some differences. The following table gives some aspects that could be considered.
