Design and experimental research of all-optical scanning device

For more precise measurements of the temporal evolution of plasma in the study of inertial confinement fusion (ICF), we analyzed a novel optical streak camera with ultrahigh time resolution. Based on the photo-generated carrier effect, waveguide transmission and prism dispersion principles, this all-optical device can avoid the influence of the space charge effect. The feasibility for the all-optical streak camera was confirmed with the experimental result. The module with prism structure to deflect the light in the waveguide was designed and fabricated. The deflection experiment was completed with the laser pulse of 8 ps (FWHM) under the condition of the signal laser wavelength of 1053 nm and the pump laser wavelength of 527 nm.
