Summary: We have developed a cost-effective spectrometer for femtosecond pulse characterization in the Near Infrared region using a Silicon-based Charge-Coupled Device (Si-CCD) sensor in two different configurations. The spectrometer achieved a resolution of 0.6 +/- 0.1 nm and a threshold peak intensity of 2 x 10(6) W/cm(2) using the Two-Photon Absorption effect in the Si-CCD sensor. We also analyzed the nonlinear response of the spectrometer and presented criteria to prevent response saturation.
