摘要： An optical fiber processing apparatus comprises reactors (3, 3a, 3b and 3c) that accommodate optical fiber, a single suction pump (7) having an intake port (19) and an outlet port (21), a storage chamber (5) into which deuterium containing gas is delivered, and a circuit portion (9, 59) including a plurality of valves disposed on a plurality of passages connecting the reactors, the suction pump and the storage chamber. The circuit portion includes a first channel for returning deuterium containing gas inside a reactor chamber to the storage chamber, a second channel for delivering air to the reactor chamber thereby rendering the pressure inside the reactor chamber atmospheric pressure, a third channel for decompression of the reactor chamber and a fourth channel for supplying deuterium containing gas in the storage chamber into the reactor chamber.

摘要： A first semiconductor laser element and a second semiconductor laser element are arranged on an identical block, a first electrode of the first semiconductor laser element is in direct contact with the block, and heat radiating effect is high. A second electrode of the second semiconductor laser element is arranged on an insulating dielectric layer, and the block and second semiconductor laser element are electrically insulated. Therefore, irrespective of the material to compose the block, the first semiconductor laser element and the second semiconductor laser element can be independently driven. In addition, the light emitting point distance between the first semiconductor laser element and second semiconductor laser element is limited only by the distance between the electrodes of the respective semiconductor lasers and the positions of light emitting points on the semiconductor laser chip end face and can, therefore, be made as short as possible.

摘要： A p-type saturable light absorbing layer is provided between p-type AlGaInP clad layers. Oxygen is doped in the p-type saturable light absorbing layer to generate non-luminescent recombination center, thereby consuming minority carrier. By this, minority carrier life of the p-type saturable light absorbing layer is lowered without saturation. Therefore, saturable light absorbing amount necessary for self-pulsation can be reduced to achieve a semiconductor laser with low threshold value, low drive current and high reliability.
摘要翻译： p型可饱和光吸收层设置在p型AlGaInP包覆层之间。氧在p型可饱和光吸收层中掺杂以产生非发光复合中心，从而消耗少量载体。由此，p型可饱和光吸收层的少数载流子寿命下降而不饱和。因此，可以减少自脉动所需的饱和光吸收量，以实现具有低阈值，低驱动电流和高可靠性的半导体激光器。

摘要： A water penetration-detecting apparatus includes an optical fiber sensor having an optical fiber, and a water-absorbent material disposed along the optical fiber in contiguous relation to the fiber. The water-absorbent material, when absorbing water, expands volumetrically so as to apply a pressure to an outer peripheral surface of the optical fiber to bend the fiber. A detecting means is connected to the optical fiber sensor for detecting a bending of the optical fiber.
