Abstract
LOS AMPLIFICADORES OPTICOS CONOCIDOS, QUE SE APLICAN EN UN TRAYECTO DE TRANSMISION DE LUZ PARA AMPLIFICAR LAS SEÑALES LUMINOSAS A TRASMITIR, TIENEN LA DESVENTAJA QUE LOS LASER DE SEMICONDUCTORES QUE SE APLICAN EN ELLOS COMO LASER DE BOMBEO SON MUY SENSIBLES A LOS EFECTOS RETROACTIVOS. DE ACUERDO CON LA INVENCION, LA CORRIENTE DE SERVICIO DE SEMEJANTES LASER DE BOMBEO (4) ESTAN MODULADA CON UNA FRECUENCIA ELEVADA CON LO QUE EL LASER DE BOMBEO TRABAJA EN UN SERVICIO MULTIMODO Y DE ESTE MODO ES INSENSIBLE A LOS EFECTOS RETROACTIVOS. POR EJEMPLO, LA CORRIENTE DE SERVICIO ES UNA CORRIENTE CONTINUA A LA QUE HAY SUPERPUESTA UNA CORRIENTE ALTERNA. EN EL CASO DE QUE EL AMPLIFICADOR OPTICO TENGA DOS LASER DE BOMBEO SE MODULA ASIMISMO SU CORRIENTE DE SERVICIO. ES VENTAJOSO CONECTAR Y DESCONECTAR ALTERNATIVAMENTE AMBOS LASER DE BOMBEO SENCILLAMENTE CON UNA FRECUENCIA DE CONEXION LO SUFICIENTEMENTE ELEVADA CON LO QUE SE IMPIDEN ANOMALIAS RECIPROCAS.
