cavcalc.functions.asymmetric.divang_of_g1g2(L, wl, g1, g2)

Divergence angle of the beam, of wavelength \(\lambda\), in a cavity of length \(L\), with mirror g-factors of \(g_1\) and \(g_2\), respectively.

\[\theta(L, \lambda, g_1, g_2) = \arctan{\left(\sqrt{ \frac{\lambda}{L\pi} \sqrt{\frac{(g_1 + g_2 - 2 g_1 g_2)^2}{g_1 g_2 (1 - g_1 g_2)}} }\right)}\]
