Abstract

PURPOSE: To suppress the production of transitional vibrations having peak values at the start of oscillation and prolong service life by making the distribution of the value of y of AlyGa1-yAs being an active layer to a value lower by 0.5 to 3% at the central part of the active layer than that at both ends and specifying this to a minimum value.
