| 英文摘要 | A method of monitoring power of laser-radiation laterally coupled from a diode-laser into an optical-fiber is disclosed. An input-end of the optical-fiber has a polished surface inclined at an angle to a longitudinal axis of the fiber. The input-end of the optical-fiber is arranged proximate an output-facet of the diode-laser such that radiation emitted from the facet is transmitted laterally into the optical-fiber and is incident internally on the polished surface. A fractionally-transmitting reflective coating is provided on the polished surface, whereby a fraction of the laser-radiation incident on the polished surface is transmitted out of the optical-fiber. A radiation-detector responsive to the laser-radiation is located in a position to receive the transmitted fraction of laser-radiation, thereby generating a signal which is interpreted as measure of power of the laser-radiation coupled into the optical-fiber. |
