摘　　要：Self-Q-switching is observed in a bulk Yb：KGd（WO4）2 oscillator without any additional modulating elements. The output power reaches 434.4 mW at a pump power of 13.67 W, corresponding to pulse repetition rate of 125 kHz and a pulse duration of 2.5μs, respectively, The mechanism of self-pulse formation is explained by the re-absorption effect of the Yb^3＋ ion in Yb：KGd（WO4）2.Self-Q-switching is observed in a bulk Yb：KGd（WO4）2 oscillator without any additional modulating elements.
