We report on the generation of 281.2 nJ mode locked pulses directly from an erbium-doped fiber laser mode-locked with the nonlinear polarization rotation technique. We show that apart from the conventional dissipative soliton operation, an all-normal-dispersion fiber laser can also emit square-profile dissipative solitons whose energy could increase to a very large value without pulse breaking.
我们报道了采用非线性偏振旋转技术锁模的掺铒光纤激光器直接产生281.2纳焦锁模脉冲的情况。我们表明，除了传统的耗散孤子运转外，全正色散光纤激光器还能发射方形轮廓的耗散孤子，其能量可以增加到非常大的值而不会出现脉冲分裂。
