\begin{minipage}[t]{\linewidth}
\begin{Box3}{}
\begin{itemize}
\item[\circleicon{red}] Higher order nonlinearity OA transmission [5]:
\begin{equation}
\displaystyle T_{mPA}(z) = 1-\displaystyle\frac{\alpha_m I_0^{m-1} L_{\text{eff}}^{(m)}}{(1 + {z^2/z_0^2})^{m-1}} \frac{1}{m^{3/2}}
\end{equation}
\item[\circleicon{blue}] Normalized Transmittance at (\(z=0\)) determined from equation (1).
\begin{equation}
\displaystyle T_{2PA}= 1-\displaystyle{\alpha_{2}I_{0}L^{(2)}_{\text{eff}}}/{2^{3/2}}
\end{equation}
\begin{equation}
\displaystyle T_{3PA} = 1 - \displaystyle{\displaystyle \alpha_{3}I_{0}^{2}L^{(3)}_{\text{eff}}}/{3^{3/2}}
\end{equation}
\item[\circleicon{highlightgreen}] $\chi^2$ is calculated by
\begin{equation}
\chi^2 = \displaystyle {\sum \frac{(O_i - E_i)^2}{E_i}}
\end{equation}
\item[\circleicon{black}] Null Hypothesis [$\text{H}_0$:] Observed non-linearity due to 2PA alone.
\item[\circleicon{accentorange}] Alternative Hypothesis [$\text{H}_1$:] Non-linearity suggests 3PA.
