We demonstrate the continuous-wave operation of a solid-state Raman laser containing a barium nitrate crystal as the Raman medium. The Raman laser, which has a singly resonant cavity, is pumped by multimode radiation. The Raman oscillation threshold is reached at ∼2 W of pump power. As much as 500 kW/cm<sup>2</sup> of Stokes power density at 60-kW/cm<sup>2</sup> pump power density is obtained in the cavity.
