Abstract

Continuous-wave operation of a diamond Raman laser is demonstrated. Low-birefringence synthetic single-crystal diamond is used and is intracavity pumped by a $\mathrm{Nd}\text{:}{\mathrm{YVO}}_4$ laser. A cw output power of $200\mathrm{mW}$ is achieved at the Raman wavelength ($1240\mathrm{nm}$), and $1.6\mathrm{W}$ of on-time output power is obtained in quasi-cw mode. Losses in the diamond ($\sim 1\%$ per pass) and thermal effects in the $\mathrm{Nd}\text{:}{\mathrm{YVO}}_4$ limit the efficiency.
