The Study Of High-Efficiently LD Driver Used In Space Laser Communication

Multinational expert has been explored space-laser communication for many years . space- laser communication is a new technology which is making a breakthrough in a few years. To use beacon-light is a kind of important means which can finish catching the space-laser communication.According to the request of beacon light in space-laser communication, the text analysis and studies on high-power semiconductor laser driver, in order to raise the efficiency, this text has analyzed various kinds of factors of wastage which is causing by high-power semiconductor laser driver, put forward several kinds of means to raise the efficiency, and applies the technology of the switch power to the high-power semiconductor laser driver. In the part of constant source, the text has designed a control circuit of high-power semiconductor laser driver which is a constant source with higher steady degree. At last the text has designed a high-power semiconductor driver with stepped down, not isolated and high-efficiency。...
