- cavcalc.functions.asymmetric.w1_of_g1g2(L, wl, g1, g2)#
Radius of the beam, of wavelength \(\lambda\), at the first mirror of a cavity of length \(L\), with mirror g-factors of \(g_1\) and \(g_2\), respectively.
\[w_1\left(L, \lambda, g_1, g_2\right) = \sqrt{ \frac{L \lambda}{\pi} \sqrt{\frac{g_2}{g_1(1 - g_1 g_2)}} }\]
