We reported the simultaneous generation and selective manipulation of scalar and cross-phase modulation instabilities in a fiber optical parametric oscillator. Numerical and experimental results show independent control of parametric gain by changing the input pump polarization state. The resonant cavity enables power enhancement of 45 dB for the spontaneous sidebands, generating laser pulses tunable from 783 to 791 nm and 896 to 1005 nm due to the combination of four-wave mixing, cascaded Raman scattering and other nonlinear effects. This gain controlled, wavelength tunable, fiber-based laser source may find applications in the fields of nonlinear biomedical imaging and stimulated Raman spectroscopy.
我们报道了在光纤光学参量振荡器中同时产生并选择性地操控标量和交叉相位调制不稳定性。数值和实验结果表明，通过改变输入泵浦偏振态可独立控制参量增益。该谐振腔能使自发边带的功率增强45分贝，由于四波混频、级联拉曼散射及其他非线性效应的共同作用，产生波长可调谐范围为783至791纳米以及896至1005纳米的激光脉冲。这种增益可控、波长可调谐的光纤激光源可能在非线性生物医学成像和受激拉曼光谱领域找到应用。
