应用c数量子朗之万方法在激光场的低阶近似下讨论了强相干驱动场下V型三能级系统无反转激光的非绝热线宽.证明了在强驱动场下，不管激光腔是"好腔"还是"坏腔"，系统的非绝热效应消失，即系统均可作绝热近似.
Nonadiabatic linewidth of a V-type noninversion laser is calculated on the basis of a c-number quantum Langevin approach in lowest order of the laser field. It is shown that when the driving field is very strong, the system behaves adiabatically whether with good or bad cavity.
