利用光纤中的多阶受激拉曼散射和声光可调谐滤波器(AOTF)，设计了可输出单一波长的黄光可调谐拉曼激光器。得到了558~583 nm内6个波长的黄激光，该激光器输出单一波长脉冲能量约为5 μJ，激光半峰全宽小于5.4 nm，脉冲宽度约为2.5 ns，发散角小于1\O。所利用的AOTF调谐为新波长可调谐拉曼激光的发展提供了一个方向。

We design a yellow light multi-wavelength tunable Raman laser by multi-stage stimulated Raman scattering in fiber and acousto-optic tunable filter, which can output a single wavelength. We get six wavelengths of yellow laser from 558 to 583 nm. Pulse energy of a single wavelength is about 5 μJ, the full-width at half-maximum of the laser is less than 5.4 nm, the pulse width is about 2.5 ns, and the divergence angle is less than 1\O. This work provides a new direction for new wavelength Raman tuning laser using tunable AOTF.
