cavcalc.functions.asymmetric.g2_of_w1w2(L, wl, w1, w2)

Stability factor of the end mirror of a cavity of length \(L\), with beam radii at the mirrors of \(w_1\) and \(w_2\), respectively; where the wavelength of the beam is \(\lambda\).

\[g_1(L, \lambda, w_1, w_2) = \pm \frac{w_1}{w_2} \sqrt{ 1 - \left( \frac{L\lambda}{\pi w_1 w_2} \right)^2 }\]
