Опис хроматске дисперзије на пертурбативан начин преко Тејлорових коефицијената је повољан за проблеме оптимизације где дисперзију из неколико различитих система треба избалансирати. На пример, код ласерских појачивача са чирпом импулса, импулси се прво растежу у времену помоћу носила да би се избегло оптичко оштећење. Затим у процесу појачања, импулси неизбежно акумулирају линеарну и нелинеарну фазу пролазећи кроз материјале. И на крају, импулси бивају компримовани у разним типовима компресора. Да би ст уклониле сви резидуални виши редови у акумулираној фази, обично се мере и балансирају појединачни редови. Међутим, за униформне системе, такав пертурбативни опис често није потребан (тј. ширење у таласоводима). Редоследи дисперзије су генерализовани на рачунски прихватљив начин, у облику трансформација Лах-Лeгерovog tipa.[ 4] [ 5]
Редослед дисперзије је дефинисан Тејлоровом експанзијом фазе или таласног вектора.
