| Abstract: | The renormalized perturbation expansion for the linewidth of the Van der Pol oscillator is extended to fifth order. The results of the previously obtained fourth order are thereby improved for pump strengthsa 5. No indication of a breakdown of the expansion, even for strong pumping, is found. |
