We demonstrate a tunable crystalline Raman laser by varying the temperature of Raman crystal. Nd:YAG and crystals were selected as the laser and Raman gain media, respectively. The center wavelength of this Raman laser was tuned over a 0.49 nm range from 1175.76 to 1175.27 nm when the temperature of the Raman crystal was adjusted from 5 °C to 150 °C. The characteristics of this Raman laser including tunability, output power, and beam quality factors () dependent on temperature were also studied in this paper.
