We demonstrate output pulse energies of 20 nJ from an erbium-doped fiber oscillator that contains only positive dispersion fibers and is mode locked by use of nonlinear polarization evolution and stabilized with a birefringent filter. The fiber oscillator operates at a repetition rate of 3.5 MHz with a central wavelength of 1550 nm. The positively chirped output pulses have a duration of 53 ps and are compressed to 750 fs. The large positive chirp of the output pulses and the steep side edges of the pulse spectrum indicate dissipative soliton operation.
我们展示了一种仅包含正色散光纤的掺铒光纤振荡器的输出脉冲能量为 20nJ，该振荡器通过非线性偏振演化进行锁模，并使用双折射滤波器稳定。光纤振荡器以 3.5MHz 的重复率工作，中心波长为 1550nm。正啁啾输出脉冲的持续时间为 53ps，并压缩到 750fs。输出脉冲的大正啁啾和脉冲光谱的陡峭边缘表明存在耗散孤子运转。
