Zusammenfassung:	A fiber laser source is configured with a plurality of individual fiber lasers which are coupled to one another in series. Each subsequent fiber laser is configured to transmit laser radiation of any of fiber laser or lasers located upstream therefrom. The switching among different operational regimes of the laser source, which includes SM, MM and different MMs and associated therewith beam shape, beam quality and power parameters is provided at high frequency corresponding to on/off switching of each individual fiber laser. Una fuente de láser de fibra se configura con una pluralidad de láseres de fibra individuales que están acoplados entre sí en serie. Cada láser de fibra subsiguiente está configurado para transmitir radiación láser de cualquiera de los láseres de fibra o láseres ubicados corriente arriba del mismo. La conmutación entre los diferentes regímenes operativos de la fuente de láser, que incluyen SM, MM y diferentes MM y asociados a la forma del haz, la calidad del haz y los parámetros de potencia se proporciona a alta frecuencia correspondiente a la conmutación de encendido/apagado de cada láser de fibra individual.
