Abstract

PARA SUAVIZAR LOS EFECTOS TERMICOS PERJUDICIALES DE LA POTENCIA DE BOMBEO EN UNA BARRA DE CUERPO SOLIDO DE LASER (1) Y PARA AMPLIAR EL GRADO DE EFECTO DEL LASER, SE ACOPLA EN UNA BARRA DE LASER (1) CON DIAMETRO EN FORMA DE POLIGONO TRIANGULAR, CUADRATICO, PENTAGONAL, EXAGONAL, UN RAYO DE UN LUZ DE TAL MANERA, QUE EL RAYO DESCRIBE EN EL INTERIOR DE LA BARRA UNA CURVATURA DE TORNILLO ANGULAR (L). EN EL DIAMETRO DE LA BARRA SE CONSIDERA, SE DESVIA EL RAYO DE LUZ (L) EN CAMPOS DISTINTOS DE LA BARRA DE TAL MANERA, QUE SE COMPENSAN LOS EFECTOS DE LOS GRADIENTES DE LA TEMPERATURA EN AMBOS SENTIDOS VERTICALMENTE PARA EL EJE LONGITUDINAL DE LA BARRA. SE PUEDE ACOPLAR VARIOS RAYOS EN SITIOS DIFERENTES, PARA QUE LOS RAYOS DESCRIBAN UNA CURVATURA DE TORNILLO HABITUALMENTE Y QUE SE ALUMBRE EL VOLUMEN DE LA BARRA LO MAS BUENO POSIBLE.
