演讲摘要：

Computer-generated hologram (CGH) allows an arbitrary spatial shape control of femtosecond laser pulse excitations, and a spatial light modulator (SLM) displaying a dynamic CGH has been used to achieve the dynamic control for material processing, nonlinear microscope, and novel information apparatus. The holographic techniquefor laser excitation of materialshas seven advantages: high-throughput with the beam splitting and shaping, high-light use efficiency, reconfigurable beam shaping, three-dimensional structures inside transparent materials, instantaneous beam irradiation in the presence of the target movement and deformation, correction of the optical system, typically, spherical aberration correction, and an adaptive wave front control of laser pulses for compensating unknown imperfections in optical system, and unpredictable mechanical movements and air disturbances.
