Abstract: PURPOSE:To obtain a highly reliable semiconductor laser in which it is hard to give rise to end face destruction caused by laser beams by connecting mesas having different widths into each taper form in the parts corresponding to resonator end faces of a semiconductor laser and at laser beam amplification regions. CONSTITUTION:Mesas 12 and 14 are formed in the direction (001) on an n-type GaAs substrate 1.
