Abstract :
Recently, high power CW operation and nanosecond fiber lasers have been used for many industrial applications. The nanosecond Yb-doped fiber(YDF) laser system using PCF (photonic crystal fiber) rod have been developed to produce 300 W. High-peak and high-average-power nanosecond-pulse lasers are susceptible to the nonlinear effects. The spectral combination of four pulsed fiber amplifiers has been demonstrated, and a output power of 1.1 kW was achieved.
