Abstract

APARATO DE LASER QUE CONSTA DE UNA CAVIDAD INTEGRADORA, AL MENOS UNA LENTE Y UN DISPOSITIVO DE FOCO FRIO QUE PROPORCIONA UNA DISTRIBUCION DE ENERGIA ALMACENADA MAS UNIFORME, MAYOR EFICACIA DE TRANFERENCIA DE ENERGIA Y NECESIDADES DE CONTROL DE TEMPERATURA RELAJADAS. EL APARATO DE LASER INCORPORA UNA VARILLA DE LASER ENCERRADA DENTRO DE UNA CAVIDAD. LA CAVIDAD INCLUYE MEDIOS DE FOCO FRIO TRANSPARENTES OPTICAMENTE CONTIGUO A Y RODEANDO LA VARILLA DEL LASER. AL MENOS SE DISPONE UN SISTEMA DE DIODO DE LASER EN UNA RELACION ESPACIADA CON RESPECTO AL EJE DE LA VARILLA. AL MENOS SE DISPONE UNA LENTE ENTRE EL SISTEMA DE DIODO Y LA VARILLA. LA LENTE TIENE UNA LONGITUD FOCAL Y SE COLOCA PARA CONCENTRAR LUZ DESDE EL SISTEMA DE DIODO DE LASER SOBRE LA VARILLA. LA CAVIDAD ESTA RODEADA POR SUPERFICIES REFLECTIVAS Y VA PROVISTA DE AL MENOS UNA ABERTURA ALARGADA A TRAVES DE ESTA PARA PASAR LA LUZ DESDE EL SISTEMA DE DIODO AL INTERIOR DE LA CAVIDAD REFLECTANTE Y EN LA VARILLA. LAS SUPERFICIES REFLECTANTES REFLEJAN LA LUZ SIN ABSORBER QUE ATRAVIESA LA VARILLA DURANTE MULTIPLES PASOS A TRAVES DE LA VARILLA DEL LASER.
