Spider
Characterization for Small Bandwidths and Longer Pulses at NIR or IR Wavelengths
Overview
The Spider is a precision tool optimized for the complete spectral and temporal characterization of laser pulses in the infrared or near infrared. Based on the patented Spider technology, it extends the existing range of APE Spider models to cover longer pulses, between 15 fs and 500 fs, at central wavelengths around ~ 0.8 µm or 1 µm. It also supports detection of the chirp sign for stretched pulses greater than 2 ps width, making it a smart choice for the alignment of pulse compressors.
True Single Shot
With its two internal spectrometers (for fundamental spectrum and upconverted interferogram) the Spider is able to simultaneously measure amplitude and phase of the same pulse. This gives it true Single shot capability. Furthermore, the Spider control software supports calculation of the temporal intensity and phase with video rate.
