| 摘 要： | 提出了一个基于自激发受激布里渊散射的波长间隔可变多波长光纤激光器.利用单模光纤中自激发产生的非线性布里渊增益和掺铒光纤的线性增益组成混合增益光纤激光器,从而使光纤激光器在室温下产生稳定的多波长输出.改变双折射光纤环镜滤波器中保偏光纤的长度,可以实现波长间隔可变多波长激光产生,提高了多波长光纤激光器操作的灵活性和实用性.实验实现了波长间隔从0.8 nm至0.076 nm可变的多波长激光产生,波长数随波长间隔减小而增加,间隔为0.08 nm的激光波长数达86.

| Abstract: | A spacing-adjustable multiwavelength fiber laser based on self-excited stimulated Brillouin scattering without external Brillouin pump is proposed.The nonlinear gain of self-excited stimulated Brillouin scattering can suppress mode competition induced by homogeneous broadening of erbium-doped fiber.With the use of a birefringence fiber loop filter,the wavelength spacing can be adjusted by changing the length of the used birefringence fiber,which makes the laser more flexible.Multiwavelength output with adjustable spectral spacing from 0.8 nm to 0.076 nm is experimentally obtained.And the wavelength number increases as the decrease of wavelength spacing. |
