cavcalc.functions.symmetric.w0_of_gsingle(L, wl, gsingle)

Radius of a beam, of wavelength \(\lambda\), at the waist position of a symmetric cavity of length \(L\) with mirror g-factors of \(g_s\).

\[w_0\left(L, \lambda, g_s\right) = \sqrt{ \frac{L \lambda}{2\pi} \sqrt{\frac{1 + g_s}{1 - g_s}} }\]
