| 英文摘要 | An optical arrangement for the feedback-free coupling of the laser emission emitted by a semiconductor laser into an optical fiber, characterized by a first optical lens for receiving the output of the semiconductor laser, a first optical isolator composed of a Faraday rotator and a polarizer following in the propagation direction of the laser emission, a second optical isolator being composed of a second Faraday rotator and a second polarizer that has a higher blocking attenuation compared to the blocking attenuation of the first polarizer being arranged between the first lens and the optical isolator. In order to use the optical arrangement in an optical heterodyne system, the blocking attenuation of at least -70 dB is obtainable in this arrangement. |
