摘要
提出一种利用四波混频增强多波长布里渊掺铒光纤激光器的方法,在激光器中使用色散位移光纤作为布里渊增益介质,通过布里渊多波长之间四波混频效应提供的参变增益展宽激光器的有效增益谱,产生高阶斯托克斯光和反斯托克斯光,增加多波长的数目并改善输出功率。分析了激光器中掺铒光纤放大器功率和布里渊抽运功率对四波混频增强效果的影响,在980 nm抽运为105 mW,外部注入1559 nm布里渊抽运为8 dBm的条件下,在1557.56~1560.78 nm之间得到了稳定的39个波长的输出。
A four-wave-mixing enhanced multi-wavelength Brillouin erbium-doped fiber laser, in which dispersion- shifted fiber is used as Brillouin gain medium is demonstrated. The gain spectrum of the laser is efficiently broadened by the parametric gain of four-wave-mixing between Stokes lines, then more high-order Stokes and anti-Stokes lines are produced. The influences of the erbium-doped fiber amplifier power and the Brillouin pump power on the four- waves-mixing enhancement effect are also investigated. A stable multi-wavelength output with 39 waves is obtained with a 980 nm pump of 105 mW and a 1559 nm Brillouin pump of 8 dBm.
