A dataset of the laser system for VIGAS

The laser system consists of a photo injector driving laser system and a scattering laser system. The photo injector driving laser system produces an ultraviolet (UV) pulses with 0.58 mJ pulse energy, 7.2 ps (FWHM) pulse width, and 10 Hz repetition rate at a central wavelength of 267 nm, which illuminates a photo-cathode to generate a high-quality electron beam.

The ICS laser system produces two alternative ultrashort laser pulses with a central wavelength of 800 nm and 400 nm, respectively, for interacting with the electron beam. An intense second harmonic (SH) laser with 0.5 J pulse energy is achieved experimentally passing a TW Ti:sapphire laser pulse through a 0.59-mm KDP crystal.
