Abstract

Oppfinnelsen vedrører en fremgangsmåte og innretning for redusering av fasestøyen i et lasersignal fra en laserkilde. Innretningen innbefatter en første strømgenerator for levering av en drivstrøm til laserkilden for tilveiebringelse av lasersignalet. En fasestøydetektor reagerer på laserbølgelengden for generering av et fasefeilsignal, og en andre strømgenerator reagerer på fasefeilsignalet for generering av en kompensasjonsstrøm som tillegges drivstrømmen til laserkilden for generering av et fasejustert lasersignal. Innretningen danner derfor en fasestabiliseringssløyfe bestående av fasestøydetektoren og den andre strømgeneratoren, for redusering av fasestøyen i lasersignalet.
