英文摘要 | PURPOSE:To improve optical properties such as uniformity of light intensity distribution, etc., by leading out plural lead wires to the electrode metallic layer provided at the surface so that each bonding position may be scattered on the part corresponding to a light emitting area. CONSTITUTION:By scattering the die-bonding positions of lead wires 3 on the light emitting area of a semiconductor laser 1, uniform current distribution, that is, gain distribution concerning the width direction of the light emitting area 4 can be obtained even in the broad area laser which has broad light emitting area 4. Accordingly, uniform light intensity distribution can be obtained. In this case, though the lead wire 3 is connected above the light emitting area on the electrode metallic layer 2 by ultrasonic welding, or the like, a good laser beam can be obtained without damaging the light emitting area 4. Hereby, if the nonuniformity of the light intensity distribution can be avoided, the deterioration of the crystal at the end of light emitting area can be avoided to improve properties. |
