主　　题：Spectrum shaping ultrafast laser digital micromirror device 

摘      要：An ultrafast spectrum programmable femtosecond laser may enhance the performance of a wide variety of scientific applications,e.g.,multi-photon *** this paper,we report a digital micromirror device(DMD)-based ultrafast pulse shaper,i.e.,DUPS,for femtosecond laser arbitrary amplitude shaping-the first time a programmable binary device reported to shape the amplitudes of ultrafast pulses spectrum at up to 32 kHz rate over a broad wavelength *** DUPS is highly effcient,compact,and low cost based on the use of a DMD in combination with a transmission *** and temporal dispersion introduced by the DUPS is compensated by a quasi-4-f setup and a grating pair,*** pulses with arbitrary spectrum shapes,including rectangular,sawtooth,triangular,double-pulse,and exponential profile,have been demonstrated in our experiments.A feedback operation process is implemented in the DUPS to ensure a robust and repeatable shaping *** total effciency of the DUPS for amplitude shaping is measured to be 27%.
