论文摘要
掺有YB的纤维激光器中的chir纤维bragg光栅允许调整净腔分散体，从而使能够访问典型的全正常分散散热耗散性孤子状态以外的脉冲动力学。这封信展示了由非线性光环镜锁定的超快渗透性维护纤维振荡器模式。使用振荡器内部使用chir的纤维bragg栅格，它可以在-0.098 ps $^2 $至+0.067 ps $^2 $及以上的净空腔分散剂中起作用。根据配置，系统可以提供稳定的脉冲，其能量最大为2.3 NJ，并且脉冲持续时间短至98 fs。
Chirped fiber Bragg gratings in Yb-doped fiber lasers allow tuning the net cavity dispersion, thus enabling access to pulse dynamics beyond the typical all-normal-dispersion dissipative soliton regime. This Letter demonstrates an ultrafast dispersion-managed all-polarization-maintaining fiber oscillator mode-locked with a nonlinear optical loop mirror. Using a chirped fiber Bragg grating inside the oscillator, it can work at net cavity dispersion in the range from -0.098 ps$^2$ up to +0.067 ps$^2$ and above at the wavelength of 1 $\mathrmμ$m. Depending on the configuration, the system can deliver stable pulses with energies up to 2.3 nJ and pulse durations as short as 98 fs.
