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558～583nm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5μJ,激光半峰全宽小于5.4nm,脉冲宽度约为2.5ns,发散角小于1°。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。
Using the multi-order stimulated Raman scattering (SAF) and acousto-optic tunable filter (AOTF) in optical fiber, a tunable Raman yellow laser emitting a single wavelength was designed. The wavelength of 558 ~ 583nm is 6 wavelength yellow laser, the laser output single pulse energy is about 5μJ, the full width at half maximum of laser is less than 5.4nm, the pulse width is about 2.5ns, the divergence angle is less than 1 °. The AOTF tuning utilized provides a direction for the development of new wavelength tunable Raman lasers.
