Abstract
A device and method are for shaping and scanning an ultrafast laser beam. The device includes a laser source configured to output a pulsed laser beam containing different frequency spectrum, a digital micromirror device (DMD) consisting of micromirrors, which are configured to receive the laser beam and shape the received laser beam with computer generated holograms, and a dispersion compensation unit, arranged before or after the DMD, which is configured to transfer the laser beam from the laser source to the DMD with a designated angular dispersion for neutralizing the first angular dispersion introduced by the DMD.
