Abstract

"PROCESSO DE ESTABILIZAçãO DE FREQuêNCIA DE UM LASER A SEMICONDUTOR". Um processo de estabilização de freq³ência de um laser a semicondutor. O processo inclui as etapas de detectar uma cadência de pulsos heterodina misturando opticamente um campo de drenagem de um circuito ressonante óptico e uma saída de freq³ência modulada do laser a semicondutor, e detectando uma fase da cadência de pulsos heterodina misturando a cadência de pulsos heterodina em quadratura com um sinal de referência de rádio freq³ência. O processo inclui adicionalmente as etapas de filtragem da fase detectada da cadência de pulsos heterodina, escalando a fase detectada filtrada da cadência de pulsos heterodina, e modulando o laser a semicondutor com a fase detectada escalada da cadência de pulsos heterodina e o sinal de referência da modulação de rádio freq³ência.
