Abstract
Generatore laser di impulsi a concatenamento modale attivo, comprendente:- una fibra attiva drogata con un drogante fluorescente;- mezzi di pompaggio della fibra attiva;- un modulatore pilotabile dall'esterno, collegato in serie a detta fibra attiva;- un filtro di selezione di lunghezza d'onda, pilotabile dall'esterno, collegato in serie a detta fibra attiva;- mezzi di estrazione di un segnale di emissione da detta fibra attiva;- mezzi di delimitazione di una cavità laser, includente la fibra attiva, i mezzi di pompaggio, il modulatore, il filtro ed i mezzi di estrazione del segnale, in cui il modulatore pilotabile è atto a generare una modulazione del segnale di emissione generato dalla fibra attiva, tale da causare un concatenamento modale del segnale di emissione oscillante nella cavità, in cui il filtro di selezione di lunghezza d'onda è costituito da un filtro monolitico a guida d'onda ottica, in essenza di componenti soggetti a modificazioni di configurazione spaziale.
