I try to build an index in two columns at the end of my slides. To do so, I use the definitions from Create index entries in beamer with 2 columns (latex-community.org):

 {\let\item\par %definitions for subitem etc 


\begin{frame}{test 1} 
\index{Laplace}Laplace transform is... \LaTeXe\ can make you happy! 

\begin{frame}{test 2} 
\printindex \end{frame} 

However, sometimes the index entry including the page numbers fits in one line, but nevertheless LaTeX makes an empty line after the entry. It looks pretty ugly... What can I do to avoid the empty lines?

It looks fine with me. Please, run 1) pdflatex, 2) pdflatex again, 3) makeindex, and post the contents of .idx and .ind files. – yo' Mar 18 '12 at 18:10
