Paper Abstract

A thin disk regenerative amplifier based on Yb:KLW (potassium lutetium tungstate) is operated in different set-ups, changing the net gain and total amount of nonlinearity during amplification. Spectrum broadening during amplification produces Lorentz-shaped pulses with an autocorrelation width of 190 fs after dispersion compenstaion. Damping of bifurcations is demonstrated by nonlinear spectrum broadening, allowing stable operation with an output energy of of nearly 400 μJ at 50 kHz.
