| 英文摘要 | PURPOSE:To extend operating life of semiconductor laser element by mounting a semiconductor laser element to the area near the center of a submount and by giving an inclination to the one side surface of the submount so that the edge of submount is not irradiated with the laser beam. CONSTITUTION:A submount 7 is composed of molybdenum or silicon and is brazed to a step 6 consisting of copper or iron through a brazing material 8. A semiconductor laser element 9 is brazed to the area near the center of mount 7 with a brazing material 10 and the one side end of submount 7 is the inclined surface 7a being cut at the angle of at least 30 degrees for the bottom surface and is coupled at the contact position with the reflecting surface 9a. Moreover, since the lower end of inclined surface 7a is coupled to the edge of stem 6. Therefore, if a semiconductor laser element 9 is placed on the area near the center of submount 7, when it emits the laser beam, the stable laser beam can be obtained without irregular reflection of laser beam. Since a semiconductor laser element 9 is coupled to the area near the center of submount 7, difference of line expansion coefficient to the semiconductor laser element 9 is reduced, suppressing the generation of strain. |
