Abstract :
We present, what is to our knowledge the first passively mode-locked Yb:KLuW thin disk oscillator. The 105 mum thin and 10 % doped Yb:KLuW thin disk crystal is pumped by a fibre coupled pump diode delivering up to 140 W pump power at a wavelength of 980 nm. Passive mode-locking is obtained by a saturable absorber mirror. In order to achieve solitary mode-locking we had to compensate for the material dispersion and Kerr-nonlinearities from both the optical components and the air inside the resonator by using negative dispersive mirrors (GTI).
