Abstract: We present an axially tapered large mode area W-fiber for high peak power femtosecond pulse propagation at 1550-nm wavelength. Our numerical simulations show pulse compression with output pulse of 36 kW peak power and 81 fs duration in down-tapered case and nearly undistorted propagation of 20 kW, 150 fs pulse in up-tapered case. Such direction dependent propagation of the pulse in the fiber should find applications in high power laser systems. © 2018 SPIE.
