摘要：

Low-birefringence (Delta n < 2x10(-6)), low-loss (absorption coefficient < 0.006cm(-1) at 1064nm), single-crystal, synthetic diamond has been exploited in a CW Raman laser. The diamond Raman laser was intracavity pumped within a Nd:YVO4 laser. At the Raman laser wavelength of 1240nm, CW output powers of 1.6W and a slope efficiency with respect to the absorbed diode-laser pump power (at 808nm) of similar to 18% were measured. In quasi-CW operation, maximum on-time output powers of 2.8W (slope efficiency similar to 24%) were observed, resulting in an absorbed diode-laser pump power to the Raman laser output power conversion efficiency of 13%.
