Abstract

LA CONEXION CREA LAS PREMISAS PARA UN PROCEDIMIENTO DE REGULACION CON EL QUE SE MANTIENE CONSTANTE, DE FORMA INDEPENDIENTE DE LA TEMPERATURA Y DEL ENVEJECIMIENTO, LA POTENCIA OPTICA EMITIDA. USUALMENTE SE CONSTRUYEN ESTOS CIRCUITOS COMO CIRCUITOS EN CASCADA DE TRES ETAPAS, QUE SE ALIMENTAN CON TENSIONES DE FUNCIONAMIENTO SUPERIORES A 5V. SE EXPONE UNA CONEXION, QUE SE PUEDE UTILIZAR DE FORMA UNIVERSAL PARA LASER COMERCIALES EN UN MARGEN DE TEMPERATURAS T = -40 GRADOS C A 100 GRADOS C Y QUE PUEDE SER ALIMENTADA CON UNA FUENTE DE TENSION ESTANDAR DE 5V. SEGUN EL INVENTO SE DISPONEN PARA ELLO EN UN PRIMER ESCALON DE LA CASCADA AMPLIFICADORES T1,T2 DIFERENCIALES, QUE ACTUAN COMO INTERRUPTORES DE CORRIENTE, Y EN UN SEGUNDO ESCALON DE LA CASCADA LAS FUENTES DE ALIMENTACION, QUE ALIMENTAN LOS AMPLIFICADORES T3,T4 DIFERENCIALES. LA SEÑAL D DE DATOS, QUE SIRVE PARA EL CONTROL DE LA CORRIENTE IMOD DE MODULACION SE CONCATENA LOGICAMENTE EN AL MENOS UNO DE LOS ESCALONES DE LA CASCADA CON UNA SEÑAL P PILOTO, QUE SIRVE PARA EL CONTROL DE LAS CORRIENTES IP1, IP2 DE LOS PILOTOS.
