We report an efficient room-temperature operation of a resonantly pumped ${\mathrm{Er}}^{3+}\text{:}{\mathrm{GdVO}}_4$ laser at $1598.5\mathrm{nm}$. The maximum continuous wave (CW) output power of $3.5\mathrm{W}$ with slope efficiency of 56% was achieved with resonant pumping by an Er-fiber laser at $1538.6\mathrm{nm}$. With pumping by a commercial laser diode bar stack, a quasi-CW (QCW) output of $7.7\mathrm{W}$ and maximum slope efficiency of $\sim 53\%$ versus absorbed pump power were obtained. This is believed to be the first resonantly (in-band) pumped, room-temperature ${\mathrm{Er}}^{3+}\text{:}{\mathrm{GdVO}}_4$ laser.
