Abstract

UN LASER COMPRENDE PRIMER Y SEGUNDO ELEMENTOS DE RETROALIMENTACION, QUE DEFINEN UNA CAVIDAD DEL LASER, Y UN MEDIO AMPLIFICADOR DENTRO DE LA CAVIDAD DEL LASER. EL MEDIO AMPLIFICADOR TIENE PRIMERA Y SEGUNDA FACETAS (5, 6), Y UN GUIAONDAS OPTICO (8) PARA GUIAR LA RADIACION OPTICA ENTRE DICHAS PRIMER Y SEGUNDA FACETAS, EN DONDE EL SEGUNDO ELEMENTO DE RETROALIMENTACION ES SELECTIVO EN LONGITUD DE ONDA, Y SE CONFIGURA EL GUIAONDAS OPTICO (8) PARA DIRIGIR LA RADIACION OPTICA CON UN ANGULO {ZE} RESPECTO A LA NORMAL DE LA SEGUNDA FACETA (6).
