Abstract :
We compute the lasing threshold and thermally driven power-shutoff characteristics of optically pumped vertical-external-cavity surface-emitting lasers. Using a quantitative numerical model, variations in the threshold and shutoff power levels are contrasted for the two approaches to the computation of the carrier recombination rates: using the AN+BN2+CN3 model with the temperature and carrier density independent coefficients, versus using recombination rates precomputed within the framework of the microscopic many-body theory.
