开式谐振腔的Q值由衍射损耗，反射损耗，耦合引入的外部损耗共同决定。
Q factor of an open resonator is determined by the diffraction loss, reflection loss and external loss introduced by coupling as a whole.
应用于空气折射率梯度对激光准直的影响和不均匀泵浦引起的激光器附加衍射损耗。
As their applications we have studied the effect of air index gradient on laser alignment and the additional diffraction loss of laser caused by inhomogeneous pump.
提高端面抽运功率占有率，可在一定程度上减小热透镜效应对振荡光束尺寸和衍射损耗的影响。
The influences of the thermal lens effect on the oscillation beam radius and diffraction loss can be reduced by increasing the proportion of the end-pumping power.
