我们提出了一个锁模，全正常色散掺铒光纤振荡器产生的输出脉冲与宽带光谱覆盖范围从1475到1620 nm。振荡器工作在109 MHz的重复频率与输出脉冲能量为1.6 nJ。锁模操作是通过使用非线性偏振演化与双折射滤波器相结合来实现的。用外部棱镜压缩器将输出脉冲去啁啾至50 fs的持续时间。
We present a mode-locked, all-normal-dispersion erbium-doped fiber oscillator generating output pulses with broadband spectra covering the range from 1475 to 1620 nm. The oscillator operates at a repetition rate of 109 MHz with output pulse energies of 1.6 nJ. Mode-locked operation is achieved by use of nonlinear polarization evolution in combination with a birefringent filter. The output pulses are dechirped with an external prism compressor to a duration of 50 fs.
