Composition and Characterization of Femtosecond Optical Lattices Using Double Axicon Holographic Pattern

Abstract

We demonstrate a method for tailoring the light structure of a femtosecond field using a double-axicon holographic pattern without compensating for additional angular dispersion elements. Tailored light structured on the femtosecond field can be obtained by creating a pair of femtoseond Bessel beams and synthesize them. The spatial property of tailored light structure on femtosecond field investigated and compared to the CW case. We also showed the temporal characteristics of the tailored femtosecond light structure can be expressed by the interference of Bessel beams with different time shift.
