| 英文摘要 | PURPOSE:To synthesize a light output by arranging semiconductor lasers on a cooling base plate having constant temperature, and by leading light beams out of optical fibers and collecting them into one while controlling the light outputs by photosensors and a light control part. CONSTITUTION:On a base plate 14 held at constant temperature through a temperature sensor 17, a temperature control part 16, and a temperature freezing element 15, semiconductor laser devices LD1-LD3 are arranged. The semiconductor laser devices LD1-LD3 are provided with optical control parts 11-13 and photosensors for monitoring; and outputs of the laser devices LD1-LD3 are modulated and threshold-level deviation and temperature drift are compensated. The light emission parts of the devices LD1-LD3 are connected to multimode step index type optical fibers 18-20 through photocouplers, etc., and output terminals are gathered. Thus, light outputs are synthesized. |
