- PATENTKRAY1. Indretning til at kompensere tidsdispersioner forbundet med generering af ultra-korte pulser med optisk frekvens (v), omfattende: - to transparente optiske diffraktionsgitre (RA, RB), som er identiske og indbyrdes parallelle og virker efter princippet Bragg diffraktion, og - to identiske prismer (PA, PB) placeret efter hinanden i området, der adskiller førnævnte diffraktionsgitre (RA, RB), kendetegnet ved, at de ydre forsider (FeA, FeB) af nævnte prismer (PA, PB) er indbyrdes parallelle og danner en non-zero vinkel (γ) med de parallelle forsider af nævnte optiske diffraktionsgitre (RA, RB).
- 2. Indretning ifølge krav 1, kendetegnet ved, at den introducerer en gruppetidsforsinkelse (tg) hvoraf variationen som en funktion af den optiske frekvens (v) kompenserer for variationen af gruppetidsforsinkelsen (tR) introduceret af en eller gruppen af elementerne af en optisk kanal op til 4th orden af Taylor serierne af nævnte forsinkelsestid (tR).
- 3. Tidsdispersion kompensationsindretning, kendetegnet ved, at den omfatter en første indretning ifølge krav 2 og en anden indretning ifølge krav 2, hvor den anden indretning er orienteret 180°i forhold tilden første indretning.
- 4. Fremgangsmåde til komprimering af laserpulser, som tidligere er udstrakt ved hjælp af en optisk dispertionsindretning, kendetegnet ved, at der anvendes en indretning ifølge et af kravene 1-3.
- 5. Fremgangsmåde til kompensering af tidsdispersion af et acousto-optisk filter, som kan eller ikke kan være programmerbart, kendetegnet ved, at den udviser en indretning ifølge et af kravene 1-3.
