| Abstract: | The output green light amplitude fluctuations of CW mode-locked frequency- doubled Nd:YAG cannot be explained by any of the existing theories of intracavity frequency- doubled.In this paper,the mechanism for suppressing the insta bility effectively by inserting a QWP inside the cavity has been analyzed theoretically and briefly.It has been fo und that the instability arises from the mode couphng between the two independent polarization modes. |

| Keywords: | Intracavity frequency-doubled QWP Coupling of polarization modes |
