I want to use the non-sequential mode simulation to shape the circular spot output from a single-mode fiber laser into a linear spot. I import the following device parameters to simulate:
1. Single-mode fiber laser 300W, fiber core diameter 20um, M2 1.05, beam divergence 140 mrad.
2. Powell Prism CAD.
But the results were poor, with strong energy at both ends of the linear spot. May I ask, is my laser light source setting wrong or Powell prism selection wrong?
Thanks very much!
