Abstract
A semiconductor laser includes at least an active layer and a saturable absorbing layer, and a compressive strain amount in the saturable absorbing layer is set to be greater than a value of compressive strain in the active layer by about 0.3% or more. Alternatively, a semiconductor laser includes at least an active layer, a saturable absorbing layer, and a light guiding layer disposed in the vicinity of the saturable absorbing layer; and a compressive strain amount in the saturable absorbing layer is greater than a value of compressive strain in the active layer by about 0.3% or more.
