The authors give a new upper bound for the diameter $D(G)$ of a graph $G$ in terms of the eigenvalue of the Laplacian of $G$. The bound is $$ D(G)\leqq \lfloor\fract{cosh^{-1}(n-1)}{cosh^{-1}\frac{\lambda_n + \lambda_2}{\lambda_n - \lambda_2}}\rfloor +1, $$ where $0\leq \lambda_2 \leq \cdots \leq \lambda_n$ are the eigenvalues of the Laplacian of $G$ and where $\lfloor \rfloor$ is the floor function.
