WebFeb 1, 2010 · By contrast, chirped mirrors (CMs) which are dispersive multilayer structures designed by optimizing the initial design are usually used for pulses compression by providing dispersion without much material in the beam path. WebHigher-order dispersion can be well controlled through the design of a chirped Bragg grating. For example, it may be tailored such that it fits well to the dispersion of a given pulse compressor in a CPA system. The same principle can also be utilized with chirped dielectric mirrors. Here, however, the possible range of group delays is very ...
