    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.

    FIGURE 1. Multiphoton, or nonlinear, microscopy, uses ultrafast laser sources for capturing high-resolution three-dimensional (3D) images with reduced photobleaching and phototoxicity compared to traditional confocal microscopy techniques. However, pulse spreading can make multiphoton microscopy images like this one become blurry.
