    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.
    This article is part three of a three-part series focused on ultrafast lasers.
