Abstract
A compact, strictly all-fiber, picosecond pulse source based on ytterbium (Yb) doped fiber is described. Stable solitary mode-locking is obtained in a fiber-oscillator utilizing a carefully designed chirped fiber-Bragg-grating (C-FBG) for both dispersion control and spectral filtering. Self-starting is assured through the use of a fiber-coupled semiconductor-saturable-absorber-mirror (SESAM). The oscillator’s 50 MHz 3.8 ps pulse-train output at 1064 nm wavelength is amplified to 1.2 W average power by an Yb-doped fiber-amplifier, yielding 6.45 ps parabolic pulses. Numerical simulations of the fiber-oscillator design based on the modified nonlinear Schrödinger equation (NLSE), agree well with the experimental results.
