| 1. | Fiber lasers are very sensitive to environmental perturbations such as temperature fluctuations and mechanical vibrations due to their relatively long cavity length when the external environment changing . the cavity drifting produceing the phase noise and amplitude noise , this can cause the output pulse unstablely
但由于主动锁模光纤激光器腔内有较长的光纤,而光纤的长度极易因外界环境的影响而发生漂移,因而调制频率和腔长很难保持匹配。 |
