AbstractWe present a revolutionary way to manipulate and steer ultrafast lasers based on a digital micromirror device (DMD). The DMD scanner performs 3D or random-access scanning, achieving a scanning speed of 22.7 kHz, scanning range of ~103 × 206 × 524 μm3, and scanning resolution (i.e., minimum step size) of 270 nm and 130 nm in the axial and lateral directions respectively when paired with a 40X objective lens. To demonstrate the performance, the DMD scanner is used to perform 3D two-photon excitation (TPE) imaging on pollen samples as well as two-photon polymerization (TPP) to fabricate 3D structures.
