    FIGURE 1. The refractive index of UV-grade fused silica as a function of wavelength (left); this dispersion can lead to temporal distortion for ultrafast laser pulses. Attempting to focus a white light source through a single lens results in different focal planes for the various component colors (right); this is analogous to how ultrashort pulses experience temporal distortion when passing through a medium.
