• An alternative method to specify the degree of resonator stability

We present an alternative method to specify the stability of real stable resonators. We introduce the degree of optical stability or the 𝑆 parameter, which specify the stability of resonators in a numerical scale ranging from 0 to 100%. The value of zero corresponds to marginally stable resonator and $S &lt; 0$ corresponds to unstable resonator. Also, three definitions of the S parameter are provided: in terms of $A&amp;D$, $B&amp;Z_{\text{R0}}$ and $g_{1}g_{2}$. It may be noticed from the present formalism that the maximum degree of stability with $S = 1$ automatically corresponds to $g_{1}g_{2} = 1/2$. We also describe the method to measure the 𝑆 parameter from the output beam characteristics and 𝐵 parameter. A possible correlation between the 𝑆 parameter and the misalignment tolerance is also discussed.
