The study on coupling technology of fan-shaped beam to fiber

It is difficult to couple the fan-shaped beam into fiber as its large divergence angles and beam size. Coupling equipment for fan-shaped beam was designed, which consists of two parts: parabolic mirror and GRIN lens. Firstly, the model of fan-shaped beam was founded. Secondly, the fan-shaped beam focalized by parabolic mirror and the beam compressed by GRIN… CONTINUE READING
