Grating-free 2.8 μm Er∶ZBLAN fiber chirped pulse amplifier
文献摘要：
We report on a grating-free fiber chirped pulse amplifier(CPA)at 2.8 μm for the first time.The CPA system adopted Er∶ZBLAN fiber with large anomalous dispersion as the stretcher and germanium(Ge)rods as the compressor with a compact structure.High-energy picosecond pulses of 2.07 μJ were generated at the repetition rate of 100 kHz.Using highly dispersive Ge rods,the amplified pulses were compressed to 408 fs with a pulse energy of 0.57 μJ,resulting in a peak power of approximately 1.4 MW.A spectral broadening phenomenon in the main amplifier was observed,which was caused by the special gain shape of the Er∶ZBLAN fiber amplifier in operation and confirmed by our numerical simulation.This compact fiber CPA system at 2.8 μm will be practical and meaningful for application fields.
