Abstract
The pump of fiber laser is a kind of laser diode module with pigtail. In the high power laser diode module, the beams of several diode emitters are shaped by lenses and combined, and coupled into a fiber called pigtail. As the power of fiber laser upgrated, the power of the high power laser diode module needed to be increased, and the tolerance of the pigtail should be higher. And then, the input end of the pigtail becomes to be the weakest part of the high power laser diode module. We developed a kind of pigtail, with high reliability and highly cost-effective, whose power tolerance could be 700W CW.
