The fiber laser concept is proven technology for telecom applications where its single mode performance and reliability is essential. Newer generation diode-pumped fiber lasers are using pump diodes especially developed for telecom applications and therefore offer excellent controllability of the laser pulse length and pulse frequency. In recent years the output power of fiber lasers has increased steadily. This high power performance enables the fiber laser to serve industrial applications like marking. High power fiber lasers are now available at power levels sufficient for micro cutting applications. This paper presents micro cutting results with pulsed fiber lasers.
