Although femtosecond microjoule Yb-fiber systems are attractive because of a straightforward power scalability, they inherently suffer from a lowered pulse fidelity as a result of complex dispersion and nonlinearity management. Here, we present an integrated Yb-fiber system delivering high-fidelity microjoule pulses compressible down to 160 fs. The system uses a dispersion compensating fiber stretcher that is specially designed to match the dispersion of a 1480 lines/mm grating compressor. Performance analysis suggests the further possibility of scaling the pulse energy to tens of microjoules without pulse quality deterioration using this dispersion management scheme.
尽管飞秒微焦耳 Yb 光纤系统因其简单的功率可扩展性而具有吸引力，但由于复杂的色散和非线性管理，其固有脉冲保真度降低。在这里，我们展示了一种集成的 Yb 光纤系统，可提供可压缩至 160fs 的高保真微焦耳脉冲。该系统使用了一种特别设计的色散补偿光纤拉伸器，以匹配 1480 线/毫米光栅压缩器的色散。性能分析表明，使用这种色散管理方案，进一步将脉冲能量扩展到数十微焦耳而不降低脉冲质量是可能的。
