Spectral linewidth and coherence

Abstract

Målet vårt har vært å gi et bidrag til studiet av bølge-partikkel dualiteten for lys, gjennom analyse av begrepet "optisk koherens". Vi har gjennomført en numerisk studie av en modell som antar at lys sendes ut som pulser av elektromagnetisk stråling, og vi har eksperimentelt bestemt den tidsmessige koherenslengen til spektrallinjen i neon som har bølgelengde 692 nm. Det eksperimentelle oppsettet viste seg å være mindre nøyaktig enn først antatt, men målingene indikerer en koherenslengde i størrelsesorden 30 mm. De numeriske simuleringene antyder muligheten for at auto-korelasjonsfunksjonen kan benyttes til å bestemme størrelsen på pulser av elektromagnetisk stråling.
