Tolerance on Tilt Error for the Incoherent Combination of Fiber Lasers in a Real Environment

We present a detailed study on the tolerance on tilt error for the incoherent combination of fiber lasers propagating in a real environment and analyze the influence of fill factor, mechanical jitter and atmospheric turbulence on tilt tolerance. Numerical results show that the tolerance on tilt error is independent of the fill factor and decreases with an increase in mechanical jitter or turbulence intensity (fundamental areas of phenomenology(including applications))
