Even distribution of carriers allows to maximize optical gain of the Optically-Pumped Vertical External Cavity Surface Emitting Laser. In this paper we show how to distribute the quantum wells and blocking layers in order to compensate the exponential decay of the pumping beam intensity. Our model says whether it is possible at all (for an assumed length of the device) and, if it is, allows to find positions of the blocking layers. No iterations nor numerical calculations more sophisticated than a standard calculator can do are required to use the model.
