Chirped mirror compressor
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 ... WebMay 25, 2024 · Here, a beam sample is taken by a broadband output coupler with 99% reflectivity and the rest of the signal is sent into a chirped-mirror compressor. In total, a dispersion of is applied to minimize the pulse duration as measured with a following auto-correlator (AC).
