| 英文摘要 | PURPOSE:To form a highly reliable, stable power source, by using a magnetooptic crystal for the material of the light emitting window of an airtight sealing cap, and arranging the end surface of the crystal at a specified slant angle with respect to the emitting light from a semiconductor laser element. CONSTITUTION:The end surface of a magnetooptic crystal 5 is arranged at a specified slant angle with respect to emitting light from a semiconductor laser element The emitting light from the element 1 is emitted through the light emitting window of a cap 1 Thereafter, the light is coupled with optical fiber 7 through a lens 2 and an analyzer 6. As reflected returning light to the element 1, only the light reflected at the end surface of the magnetooptic crystal 5, which is used for the material of the window, on the side of the semiconductor element is considered. Then the reflected returning light can be made very little. Only the light having the extinction ratio of the magnetooptic element of, e.g., -40 dB, is returned to the element 1, with respect to the light, which is reflected by optical parts such as the lens and the like that are located at points further than the crystal 5 from the element Since a semiconductor laser module having an optical isolator is sealed in an airtight manner in this way, high reliability is obtained. |
