Abstract

All integrated mode-locked Yb-doped fiber oscillators delivering high fidelity pulses are very attractive as seed sources for Yb-fiber amplifier systems [1] as well as Yb solid state lasers [2] delivering sub-200 fs pulses. The main demands for seed sources of such systems are good pulse quality and compressibility, and enough seed energy. High fidelity pulses are also beneficial to minimize collateral damage in applications like micromachining and microsurgery. The requirement for pulse energy and pulse fidelity becomes even more demanding for phase stabilized amplifier systems [3] requiring sub-100 fs pulses with pulse energy of several nJ. The robustness and stability of fiber oscillators offer an interesting alternative to solid state oscillators.
