Best Answer

It is very close to the boondox calligraphic font:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}

\usepackage{boondox-cal}

\pagestyle{empty}

\begin{document}%

$ \begin{array}[t]{c@{\quad}c}
\multicolumn{2}{l}{\mathbf{Boondox:}}\\
\verb+ \mathcal + & \verb+ \mathbcal + \\[6pt]
     \mathcal{L l} & \mathbcal{L l}
    \end{array} $

\end{document}
