| 摘 要： | 报道了从一个典型的基于非线性偏振旋转被动锁模光纤激光器中产生双波长锁模脉冲的研究。双折射诱导的波长相关腔传输使得激光器能同时在2个或多个波长上振荡,本文设计的激光器中最多有3个波长同时产生。由于偏振相关隔离器(PDI)引入的另外偏振相关腔损,通过调节偏振控制器(PC),3个波长中的任意2个能同时共振,并同时锁模。此外,双波长脉冲中2个不同波长的脉冲会相互作用,并通过交叉相位调制形成各种各样的调制格式。

| Abstract: | The operation of a passively mode-locked erbium-doped fiber ring laser in two-wavelength pulse mode has been experimentally demonstrated.Multiple wavelengths can simultaneously oscillate owing to the wavelength-dependent transmission induced by birefringence.Due to additional polarization dependent cavity loss imposed by polarization dependent isolator,two-wavelength mode-locked pulses can be obtained.The wavelengths of two-wavelength mode-locked pulses can be switched among three wavelength bands.Furthermo... |
