High Time-Resolved Three-Dimensional Imaging Using Ultrafast Optical Kerr Gate of Bismuth Glass

We have demonstrated the high time-resolved three dimensional (3-D) imaging using a chirped supercontinuum (SC) and an ultrafast optical Kerr gate (OKG) generated with a femtosecond laser, in which a sapphire plate and a Bi

oxide glass (BI glass) were used to generate the chirped SC and the optical Kerr gate, respectively. The experimental results show that the 3-D imaging using BI glass offers better temporal and longitudinal spatial resolution compared with CS
