Intracavity continuous-wave (CW) multiple stimulated-Raman-scattering emissions have been successfully demonstrated in a KTP crystal pumped by a Nd:YVO(4) 1064-nm laser for the first time. Three different output couplers (OCs) with high-reflection (HR) coating in the range of 1-1.1, 1-1.13, and 1-1.15 μm are employed in the experiment to generate lasing wavelengths at 1095 (the first-Stokes emission of the 266 cm(-1) Raman shift), 1095 + 1128 (the first- and second-Stokes emission of the 266 cm(-1) Raman shift), and 1095 + 1128 + 1149 nm (the first two Stokes emissions of the 266 cm(-1) Raman shift and the first-Stokes emission of the 694 cm(-1) Raman shift), separately. This Raman laser paves a way to produce more-closely spaced set of CW emission in the green-yellow region.
