Abstract
PURPOSE: To prevent eh d eterioration of the resonances surface with suppression of the increment for the oscillation start current density and thus to ensure the longlife characteristics, by covering the both resonance surfaces of the semiconductor laser element with the dielectric film which is set to a specified thickness.
