WebMay 1, 1997 · We present a grating pair based on Carpenter prisms whose third-order dispersion is opposite that of a traditional grating pair. A properly designed stretcher{endash}compressor system with these gratings has the unique characteristic that it simultaneously compensates for second- and third-order dispersion as a function of … WebMay 20, 1997 · We propose a ray-tracing model that provides a clear physical picture and simple formulas for grating pair stretcher dispersion calculations. With this model we can easily demonstrate why and to what extent the stretcher and compressor are opposite quantitatively without using a Fourier transform. The dispersion calculation shows that the ...
