在被动锁模色散管理掺镱光纤激光器中观察到了光谱调制深度可变的孤子分子。我们实验研究的孤子分子呈现出双原子和四原子两种类型。随着抽运功率的增加，激光器交替地工作在孤子分子态、时间分离振荡孤子态和谐波锁模态。此外，孤子分子的相位只在低泵浦时才被锁定，而过高的泵浦会引起相位振动。
We have observed soliton molecules with variable modulation depth of spectra in a passively mode-locked dispersion-managed Yb-doped fiber laser. The soliton molecule we experimentally investigated presents diatomic and tetratomic types. With the enhancement of pump power, the laser alternately operates at solitons molecule, temporal-separation-oscillation solitons, and harmonic mode-locked states. Moreover, the phase of solitons molecule is only locked at low pump, and excess pump would cause phase vibration.
