We report a linear-cavity high-power all-solid-state Q-switched yellow laser. The laser source comprises a diode-side-pumped Nd:YAG module that produces $1064\mathrm{nm}$ fundamental radiation, an intracavity $\mathrm{Ba}\mathrm{W}{\mathrm{O}}_4$ Raman crystal that generates a first-Stokes laser at $1180\mathrm{nm}$ , and a KTP crystal that frequency doubles the first-Stokes laser to $590\mathrm{nm}$ . A convex-plane cavity is employed in this configuration to counteract some of the thermal effect caused by high pump power. An average output power of $3.14\mathrm{W}$ at $590\mathrm{nm}$ is obtained at a pulse repetition frequency of $10\mathrm{kHz}$ .
