Abstract: The 8-shaped 4-mirror ring resonator containing two flat mirrors and two concave mirrors is widely used in color center lasers, laser gyroes and other research fields. With the model of a thermal thin lens, we give an equivalent linear cavity to analyst its beam characteristics. The thermal influences on its basic properties are discussed in detail. And the insensitive condition of the 4-mirror ring resonator to thermal thin lens is given. The results are useful to guide the resonator design and its application.
