The rapid evolution of ultrafast optics technology over the past two decades has opened the window to a broad range of applications in biology and medicine. Compact, reliable, and turn-key ultrafast laser systems are enabling cutting-edge science to take place in everyday laboratories and clinics. Led by the discovery of two-photon excitation fluorescence microscopy nearly 20 years ago, the biological imaging community is exploring unique image contrast mechanisms and pushing spatial and temporal resolution to new limits. Concurrent with advancements in imaging are developments in the precision application of extremely high peak intensities available in ultrashort pulses for disrupting or manipulating targeted locations in biological systems on the submicron scale while leaving surrounding tissue healthy. The ability for scientists to selectively discriminate structures of interest at the cellular and subcellular levels under relevant physiological conditions shows tremendous promise for accelerating the path to understanding biological functions at the most fundamental level.
