Fig. 2

Stretched pulse waveforms are measured under several conditions of a pair of flat mirrors in the FACED system. a Mirror-pair-distance (d) dependence on the temporal interval of the sub-pulses (Δt). The results show good agreement with the theoretical relation, Δt ∼ 2d/c, where c denotes the speed of light. b Mirror-pair-angle (α) dependence on the number of sub-pulses (N). The results show good agreement with the theoretical relation, N ~ θ/α, where θ denotes a constant value determined by a FACED geometry.
