Abstract
UN SISTEMA OPTICO CON UN AMPLIFICADOR (20) OPTICO QUE CONTENGA UNA SUSTANCIA ACTIVA PARA EL LASER, DICHA SUSTANCIA SE EXCITE MEDIANTE LA LUZ DE BOMBEO A UN NIVEL DE ENERGIA METASTABLE, CONTIENE, ADEMAS DEL LASER (2) QUE GENERA LA LUZ REFORZABLE (LAMBDA2), UN SEGUNDO LASER (3) QUE MEDIANTE SU LUZ DE SALIDA SE PUEDE CONTROLAR LA AMPLIFICACION DE LA LUZ A AMPLIFICAR. ESTO TIENE LUGAR PORQUE MEDIANTE LA ABSORCION DE LA LUZ (LAMBDA3) DEL SEGUNDO LASER (3) SE CONSIGUEN TRANSICIONES DE LA SUSTANCIA ACTIVA DESDE EL NIVEL METASTABLE A UN NIVEL MAYOR DE MODO QUE SE PUEDE INFLUIR LA OCUPACION DEL NIVEL METASTABLE, DEL QUE DEPENDE LA AMPLIFICACION DE LA LUZ A AMPLIFICAR. UN PRIMER CASO DE APLICACION PARA EL NUEVO SISTEMA OPTICO ES UN SISTEMA DE TRASMISION DE INFORMACIONES, EN LA QUE SE PUEDE CONVERTIR LA LONGITUD DE ONDA DE LA SEÑAL OPTICA A TRASMITIR A LA LONGITUD DE ONDA DE LA LUZ AMPLIFICABLE POR EL AMPLIFICADOR OPTICO (20). UN SEGUNDO CASO DE APLICACION ES UN SISTEMA OPTICO DE TRASMISION DE INFORMACIONES EN EL QUE LA AMPLIFICACION DE UNA SEÑAL OPTICA A TRASMITIR DEBE SER CONTROLABLE OPTICAMENTE O MODULABLE ADICIONALMENTE MEDIANTE UNA O VARIAS SEÑALES ADICIONALES.
