摘要
使用四端口环行器和可调谐滤波器,设计了一种间隔为双倍布里渊频移的多波长布里渊掺铒光纤激光器.该光纤激光器中使用的四端口环形器可以限制奇次阶斯托克斯光在腔内循环并耦合输出初始泵浦光和偶次阶斯托克斯光,而可调滤波器抑制环形腔所形成的自激振荡模,增加了激发多波长激光的功率,从而增加多波长输出个数及其调谐范围.在布里渊泵浦功率为8 dBm、980 nm泵浦功率为279 mW时,实验获得波长间隔为0.173 nm的6个波长的激光输出,输出激光的可调谐范围为28 nm.
Abstract
A tunable multiwavelength brillouin/erbium fiber laser with doubleBrillouinfrequency spacing based on a fourport circulator was experimentally demonstrated. The fiber laser configuration formed by fourport circulator isolates the oddorder brillouin stokes signal to circulate within the cavity only. In addition, it also allows propagation of the incoming brillouin pump and evenorder Stokes signals from fourport circulator to output coupler. A fiber FabryPerot tunable filter was used to manipulate the location of selflasing cavity and to increase power for multiwavelength oscillation. It can be obtained that a wideband tuning range and more output channels. At the brillouin pump power of 8 dBm and the 980 nm pump power of 279 mW, 6 output channels with 0.173 nm spacing and tuning range of 28 nm from 1535 nm to 1563 nm were achieved.
