FIGURE 1. Three-photon excitation uses 3x the wavelength as conventional one-photon absorption. The 1300 nm excitation scheme shown here is for GCaMP6s, a genetically expressed calcium indicator. Recently Chris Xu and colleagues have demonstrated that 1300 nm can also excite longer-wavelength dyes such as Texas Red, a fluorescent dye that can be bonded to antibodies to label specific cellular components.
