Multidimensional ultrashort optical pulse manipulation using spatial light modulation.

ABSTRACT

Ultrashort optical pulse manipulation is one of the key techniques for applications such as high-speed imaging and high-precision laser processing. In this study, we demonstrate the multidimensional manipulation of ultrashort optical pulses by integrating spatial dispersion and spatial light modulation. Specifically, by modulating the phase of each wavelength, we achieve arbitrary adjustments in multiple dimensions, including number of sub pulses, time interval, intensity, and pulse width simultaneously and independently with a simple setup and few calculations. The performance of the optical pulse manipulation method is verified through both numerical simulations and experiments.
