摘　　要：对泵浦带有弛豫振荡的固体激光器的弛豫振荡特性进行了系统的理论研究,发现实际光子数的起伏同时具有自身固有的弛豫振荡频率和泵浦光的弛豫振荡频率两种分量。当两者的频率相近时,会呈现出共振加强现象。特别是当两个弛豫振荡的衰减率也相等的时候,共振现象极为强烈。 PD反馈能够有效地抑制弛豫振荡。The relaxation oscillation in solid-state laser with relaxation oscillation pumping was studied theoretically. The undulation of the laser photon density contains relaxation oscillation frequency itself and that of pumping. When those two frequencies are close, the oscillation will be resonated. Especially, when the decay rates of the two frequency oscillations are same, the resonation will be strengthened greatly. PD feedback can restrain the relaxation oscillation effectively.
