Spatial-Temporal-Property Analysis of Ultrashort Pulse Propagating Through Real Optical System
The spatial-temporal property of ultrashort pulse is greatly influenced by optical aberrations, manufacturing surface-profile errors as well as element decenter and tilts when propagating through real optics. Hence it is necessary to develop a powerful analytic tool to simulate these effects. An efficient numerical algorithm based on a combination of wave theories and geometrical ray-tracing to simulate the propagation of ultrashort laser pulse through real optics is proposed. Using this tool, the spatial-temporal evolution of a Gaussian temporal envelope pulses with initial durations of 30 fs and a carrier wavelength of 800 nm through a specific real optics is modeled, in which both the geometrical aberrations and manufacturing surface-profile errors of the optical elements are considered. Consequently, a comparative analysis on focusing properties of the pulse such as temporal envelope and focal size retrieved by simulation and experimental measurement is carried out at the focus for homogeneous illumination beams.
