Abstract

LOS AMPLIFICADORES CONOCIDOS DE FIBRA OPTICA, QUE SON UTILIZADOS EN UN TRAMO DE TRANSMISION DE LUZ PARA LA INTENSIFICACION DE LA SEÑAL DE LUZ A SER TRANSMITIDA, TIENEN LA DESVENTAJA DE QUE EN ELLOS EL LASER SEMICONDUCTOR UTILIZADO COMO LASER BOMBEADO ES SENSIBLE AL EFECTO RETROACTIVO, DE FORMA QUE LA ESTABILIDAD DE LA TRANSMISION DE LA SEÑAL DE LUZ ESTA INFLUENCIADA POR MEDIO DE LAS RETROREFLEXIONES DE LUZ EN EL LASER BOMBEADO. SEGUN LA INVENCION LA CORRIENTE DE SERVICIO DE LASER (4) BOMBEADO DE ESTE TIPO CONTIENE UNA CORRIENTE DE RUIDO, DE FORMA QUE EL LASER BOMBEADO EMITE SU LUZ BOMBEADA EN MULTIPLES MODOS Y CON ELLO ES INSENSIBLE AL EFECTO RETROACTIVO. CON ELLO LA PORCION DE RUIDO QUE SE EFECTUA A TRAVES DE LA CORRIENTE DE RUIDO DE LA LUZ BOMBEADA NO REPERCUTE SOBRE LA AMPLIFICACION DE LA SEÑAL DE LUZ A SER TRANSMITIDA, ESTANDO LA CORRIENTE DE RUIDO FILTRADA DE TAL MODO, QUE SU PORCION ESPECTRAL DISPONE DE FRECUENCIAS, QUE SE ENCUENTRAN FUERA DE LA DURACION RECIPROCA DEL NIVEL DE ENERGIADE LA SUSTANCIA ACTIVA DE LASER, QUE EFECTUA LA AMPLIFICACION DE LA SEÑAL DE LUZ.
