We consider a new approach to estimating the irrationality measure of numbers that are values of the Gauss hypergeometric function. Some of the previous results are improved, in particular, those concerning irrationalities of the form $\sqrt{k}\ln((\sqrt{k}+1)/(\sqrt{k}-1))$ with $k\in\mathbb N$.
Keywords: Gauss hypergeometric function, irrationality measure, Laplace method
Mots-clés : rational fraction, Laurent series.
