论文摘要
对于许多应用,在模式锁定激光器中生成稳定的短脉冲脉冲至关重要。模式锁定是一个广泛的概念,它包含不同的过程,可以使短脉冲形成。通常,它需要一种区分单个和集体模式激光的腔内机制,这可能很复杂,有时会增加噪声。此外,已知模式锁定方案不能保证载波波的相位稳定性。从理论上讲,我们在这里提出,注射一个失去的信号无缝导致纤维激光器中的模式锁定。我们表明,类似于空腔孤子的相锁脉冲存在于广泛的参数中。在该方案中,由于非持续增益饱和,激光作为被动谐振器。
The generation of stable short optical pulses in mode-locked lasers is of tremendous importance for many applications. Mode-locking is a broad concept that encompasses different processes enabling short pulse formation. It typically requires an intracavity mechanism that discriminates between single and collective mode lasing, which can be complex and sometimes adds noise. Moreover, known mode-locking schemes do not guarantee phase stability of the carrier wave. Here we theoretically propose that injecting a detuned signal seamlessly leads to mode-locking in fiber lasers. We show that phase-locked pulses, akin to cavity solitons, exist in a wide range of parameters. In that regime the laser behaves as a passive resonator due to the non-instantaneous gain saturation.
