Both Theoretical and Experimental Analysis of Temporal and Spatial Chirp of Femtosecond Pulse Beam in a Prism Pair

Abstract:

Spatial and temporal chirp will effects a pulse both in space and in time domains. So effectively controlling and utilizing the spatial and temporal chirp has great significance. In this manuscript, firstly the dispersion properties of the prism pair is theoretical analyzed, and the phase delay second derivative expression of the thin prism is obtained. Then a setup is demonstrated to experimentally investigate the spatial and temporal properties of the femtosecond pulse beam. The spatial chirp and temporal chirp effects on the femtosecond pulse beam are experimentally obtained. Both theoretical analysis and experimental results indicate that the group delay dispersion due to prisms is always negative, and the pulse beam can be compressed or broadened by the prism pair based on changing the prisms referring parameters.
