| 摘 要： | 提出并实现了一种以高非线性色散位移光纤为增益介质,以光栅对形成谐振腔,简单线形结构的连续光抽运的波长间隔可调谐多波长光纤光学参量振荡器(MW-FOPO)。采用波长可调谐的窄线宽激光器作为抽运种子光源,以伪随机相位调制抽运光来抑制高非线性光纤中的受激布里渊(SBS)散射效应,结合高功率掺铒光纤放大器构成光纤光学参量振荡器的大功率抽运,通过四波混频(FWM)效应获得了室温下稳定的多波长激光输出。MW-FOPO的波长间隔可以通过调节抽运波长进行调谐。在1505~1615 nm光谱范围内,获得了17条消光比大于10 dB的多波长谱线。实验证明了MW-FOPO实现多波长激光光源的优异特性。

| Abstract: | A wavelength-spacing tunable multi-wavelength fiber optical parametric oscillator(MW-FOPO) with a simple line cavity is proposed.A tunable laser provides the pump seed light.A pseudorandom modulation method is used to broaden the line-width of the pump seed light by employing a phase modulator,which can successfully suppress the stimulated Brillouin scattering(SBS) when the high power pump light is injected into the highly nonlinear optical fiber(HNLF).A high power erbium-doped fiber amplifier is used to ac... |
