Abstract

AMPLIFICADOR DE LASER EN EL QUE EL INDICE REFRACTARIO EFECTIVO DE LA REGION ACTIVA DE LOS MODOS ELECTRICO TRANSVERSAL Y MAGNETICO TRANSVERSAL SON LO SUFICIENTEMENTE DIFERENTES COMO PARA PROPORCIONAR SOLAPAMIENTO DE ONDULACION DE FRECUENCIA DE MODO MULTIPLE DE UNA CRESTA ENVOLVENTE DE 3 DECIBELIOS DE GANANCIA. LA REGION ACTIVA ESTA REALIZADA DE FORMA ALTAMENTE ASIMETRICA CON UNA PROPORCION DIMENSIONAL DE AL MENOS 10:1 Y PREFERENTEMENTE 20:1 CON EL FIN DE PROPORCIONAR UNA DIFERENCIA DE INDICE REFRACTARIO EFECTIVO. LOS SALTOS, GRADUACION O DIFERENCIA UNIFORME EN EL INDICE DEL MATERIAL REFRACTARIO PUEDEN ASIMISMO UTILIZARSE. LA RELACION DE FACTOR DE LIMITACION SE HACE LO MAS ALTA POSIBLE PARA PROPORCIONAR UN INDICE REFRACTARIO DE DIFERENCIA DE MATERIAL EN LAS DIMENSIONES ORTOGONALES DE LA SECCION TRANSVERSAL DE LA REGION ACTIVA.
