We report a continuous-wave Nd:GdVO(4) self-Raman laser generating wavelength-selectable output in the green-yellow spectral region. The laser combines stimulated Raman scattering (SRS) with intracavity second harmonic and sum-frequency generation (SHG/SFG) to enable "on-demand" operation at any one of three wavelengths, 532 nm, 559 nm and 586 nm, each with output power greater than 3.5 W. Using experimental and numerical modelling results, we show how the highly-interactive, simultaneous non-linear processes of SRS and SHG/SFG may be balanced to achieve stable, selectable multi-wavelength visible operation.
我们报道了一种连续波Nd:GdVO(4)自拉曼激光器,它在绿黄色光谱区域产生波长可选择的输出。该激光器将受激拉曼散射(SRS)与腔内二次谐波和和频产生(SHG/SFG)相结合,能够在532nm、559nm和586nm这三个波长中的任意一个波长上进行“按需”操作,每个波长的输出功率都大于3.5W。利用实验和数值模拟结果,我们展示了如何平衡SRS和SHG/SFG高度相互作用的同时非线性过程,以实现稳定、可选择的多波长可见光操作。
