The minimum splicing loss of 0.58 dB is achieved experimentally with this approach, Meanwhile, the power capacity of this splicing joint is also tested with a high power fiber laser. The maximum input power is up to 15 W, only limited by the available power of the laser source. To the best of our knowledge, this is the first report on thermal splicing between fluoride and silica fibers operating in a high power regime without any complicated ion-assisted deposition process.展开更多

This was reiterated by J. C. Mackay, Senior Vice President and General Manager of Spar Space Systems, when he met April 4 with Bai Baier, Vice President of CASC. During the meeting Spar briefed their Chinese counterparts on the status of Radarsat-1, launched last November aboard Delta-2 rocket., the satellite, with Synthetic Aperture Radar (SAR) as its principal instrument, has just finished its commissioning phase and been declared operational by its user, the Canadian Space Agency (CSA).
