The coherent combining of single mode lasers using coupled cavities is considered. A simple analytical estimate of the number of lasers that can be efficiently combined in such a way is suggested. Such an estimate agrees with simulations and experiments reported recently.

Key words: coherent beam addition, laser addition, coherent beam combining, power scaling
