Abstract：We demonstrate a diode pumped Yb:LuVO$_{4}$ laser that can be passively Q-switched by a Cr$^{4+}$:YAG saturable absorber having an initial transmission as high as 99.3%. A maximum pulsed output power of 2.35 W is generated at a repetition rate of 285.7 kHz, approaching or very near the intrinsic upper limit imposed by the recovery time of the Cr$^{4+}$:YAG saturable absorber, and the resulting pulse energy, duration and peak power are, respectively, 8.2 $\mu$J, 39.2 ns and 0.209 kW.
