摘要：

We present a totally fiber integrated chirped-pulse amplification system using air-core photonic bandgap fiber and a conventional erbium-doped fiber amplifier. similar to40-ps input pulses, generated in a Mach-Zehnder modulator, were stretched and spectrally broadened in a dispersion-shifted fiber before being amplified and subsequently compressed in 10 m of anomalously-dispersive photonic bandgap fiber to yield similar to960 fs pulses. The system gives multi-kilowatt peak powers while the amplifier nonlinearity threshold is as low as similar to150 W. Higher peak powers could be obtained by the use of an amplifier with higher nonlinearity threshold. (C) 2004 Optical Society of America.
