We present the characteristics of a folded-cavity actively Q-switched intracavity frequency-doubled Raman laser in which a KTP crystal is used as the frequency-doubling material, an Nd∶YAG crystal is used as the gain medium and an SrWO4 crystal as the Raman medium. The dependences of the average output power, the pulse energy and width on the pulse repetition rate and incident LD pump power are given. When the incident pump power is 12.6 W and the repetition rate is 20 kHz, the average output power is 1.4 W, and the corresponding conversion efficiency from the diode laser to yellow laser is 11.1%. When the incident pump power is 12.6 W and the repetition rate is 10 kHz, the pulse energy is 122 μJ, the pulse width is 4.0 ns, and the corresponding peak power is 30.5 kW.
