Kilowatt-class single-frequency fiber sources

Kilowatt-class single-frequency fiber sources
We discuss the dramatic development of high-power fiber laser technology in recent years and the prospects of kilowatt-class-single-frequency fiber sources. We describe experimental results from an ytterbium-doped fiber-based multi-hundred-watt single-frequency, single-mode, plane-polarized master-oscillator power amplifier (MOPA) operating at 1060 nm and a similar source with 0.5 kW of output power, albeit with a degraded beam quality (M2 = 1.6) and not linearly polarized. Experiments and simulations aimed at predicting the Brillouin limit of single-frequency system with athermally broadened Brillouin gain are presented. These suggest that single-frequency MOPAs with over 1 kW of output power are possible. In addition, the power scalability of a simple single-strand fiber laser to 10 kW is discussed

Abstract

We discuss the dramatic development of high-power fiber laser technology in recent years and the prospects of kilowatt-class-single-frequency fiber sources. We describe experimental results from an ytterbium-doped fiber-based multi-hundred-watt single-frequency, single-mode, plane-polarized master-oscillator power amplifier (MOPA) operating at 1060 nm and a similar source with 0.5 kW of output power, albeit with a degraded beam quality (M2 = 1.6) and not linearly polarized. Experiments and simulations aimed at predicting the Brillouin limit of single-frequency system with athermally broadened Brillouin gain are presented. These suggest that single-frequency MOPAs with over 1 kW of output power are possible. In addition, the power scalability of a simple single-strand fiber laser to 10 kW is discussed
