Figure 2
Demonstration of modified matrix analysis for laser pulse compressor. Red, blue and green line represent optical paths for each frequency component. (a) Schematic of laser pulse compressor. The center wavelength of the pulse is 810 nm, and the incident angle of the pulse at the first diffraction grating is 63 degrees (Littrow angle), and the separation distance between the diffraction grating pair is 1 cm. (b) Group delay, (c) group-delay dispersion, and (d) third-order dispersion of the laser pulse compressor evaluated by analytical formula (blue solid line), modified matrix (red circle) and original Kostenbauder matrix (grey dashed line).
