Abstract (in Japanese) (See Japanese page) 
(in English) The quantum dot semiconductor lasers have a property of narrow spectrum line width and low level threshold current, and the oscillation characteristics of the lasers are more stable characteristic to temperature variation than the conventional semiconductor lasers. In the quantum dot lasers, generally a lot of quantum dots are configured in the active region, and sufficient gains of light power are obtained. In this paper, the stochastic equations are applied to the probabilities for the numbers of electrons and holes in a dot, and the interactions between electrons, holes, and photons are considered on the probabilities. As the results the oscillation characteristics based on the deferent numbers of electrons and holes are analyzed. It is shown that the efficiency of the laser depends on the difference of electron injection and hole injection currents.
