Abstract

SUMINISTRO DE ENERGIA PARA LASER GASEOSO EXCITADO POR RADIO FRECUENCIA. EL SUMINISTRO DE ENERGIA INCLUYE UN OSCILADOR (20) QUE GENERA UNA SEÑAL DE RADIO-FRECUENCIA AMPLIFICADA POR UN AMPLIFICADOR (21). LA SEÑAL AMPLIFICADA SE APLICA A UN LASER (22) PARA INICIAR Y MANTENER UNA DESCARGA EN EL MEDIO ACTIVO GASEOSO DE LASER. SE PROPORCIONAN MEDIOS DE CONTROL DE ENERGIA (24) OPERABLES DESPUES DE LA INICIACION DE LA DESCARGA PARA AJUSTAR LA ENERGIA APLICADA AL LASER HASTA EL VALOR REQUERIDO PARA OPERAR EL LASER A EFICIENCIA MAXIMA. PUEDE PROPORCIONARSE MEDIOS DE CONTROL DE GANANCIA AUTOMATICOS (25) QUE RESPONDAN A LA SALIDA DE UN MEDIDOR DE ENERGIA.
