The precessional magnetization dynamics of a chromium dioxide (100) film is examined in an all-optical pump-probe setup. The frequency dependence on the external field is used to extract the uniaxial in-plane anisotropy constant. The damping shows a strong dependence on the frequency, but also on the laser pump fluence, which is revealed as an important experimental parameter in this work: above a certain threshold further channels of energy dissipation open and the damping increases sharply. This behavior might stem from spin-wave instabilities.
