一种新颖的多波长振荡光纤激光器

A New-type Multiwavelength Fiber Laser

提出了由两个光纤圈构成反射腔镜的光纤激光器。利用单模光纤的双折射,使光纤圈的反射率随波长呈周期性的变化。在理论上分析了光纤圈中单模光纤的长度、双折射参数对反射特性的影响。

A new type multiwavelength fiber laser whose reflectors are composed of two fiber loops is presented in this paper.Utilizing the birefringence in single mode fiber,we can make reflectivities of these fiber loops vary periodically with the wavelength.Influence of the length of sing mode fiber and the birefringence parameter in fiber loops on reflection characteristics is theoretically analyzed.And multiwavelength output is also observed in this experiment.
