Paper Abstract
Because of the diversified properties Fiber Laser affords a wide field of application. But restricted by nonlinear effects,
heat damage and other elements, it is impossible to increase the output power unlimitedly. When single fiber can't meet,
it needs to use Fiber Laser through beam combination to get high output power. Undoubtedly combiners play an
important role for increasing the output power of Fiber Laser. The advent of Photonic crystal fiber (PCF) abound the
kinds of combiners. It has numerous benefits and widespread application value. First, build the model of PCF combiners.
Then through Finite Difference Method(FDM), calculate the effect of PCF combiners on the whole loss under different
lengths of transition zone. Finally, compare the results. Through the results of numerical simulation calculation: when
the length of Transition zone L is shorter than the diffraction length of the tapered L0, loss will go down with the increase
of L; however, when L is far longer than L0, the increase of L will have negligible effect on the decrease of loss. So the
conclusion is significant to both increase the performance of Photonic crystal fiber combiner and decrease the loss.
