级联的c切Nd：YVO 4晶体自拉曼操作被证明具有259 cm− 1的拉曼位移。具有890 cm-1的主拉曼位移的斯托克斯振荡被抑制，并且基于合适的涂层设计实现了具有259 cm-1的单个拉曼位移的级联自拉曼。在泵浦功率为13.3W时，获得了波长为1129 nm的二阶斯托克斯激光输出，输出功率为0.81W。随着泵浦功率的增加，在1129和1163 nm处获得了双斯托克斯光。在泵浦功率为14.9W，脉冲重复频率为15 kHz时，获得最大输出功率为1.0W，转换效率为6.7%。
A cascaded c-cut Nd: YVO 4 crystal self-Raman operation was demonstrated with a Raman shift of 259 cm− 1. The Stokes oscillation with a primary Raman shift of 890 cm− 1 was suppressed and a cascaded self-Raman with a single Raman shift of 259 cm− 1 was realized based on suitable coating design. At an incident pump power of 13.3 W, the second Stokes at 1129 nm was obtained as the main output laser and the output power was about 0.81 W. As the incident pump power increased, dual Stokes at 1129 and 1163 nm were obtained. A maximum output power of up to 1.0 W with a conversion efficiency of 6.7% was achieved at an incident pump power of 14.9 W and a pulse repetition frequency of 15 kHz.
