Double-end-pumped double Nd:YVO4 crystals continuous green laser

  • 摘要: 为了提高半导体激光器抽运的全固态激光器的输出功率与光-光转换效率,设计并使用了双端抽运双Nd:YVO4绿光激光器。通过激光晶体温度场特性的研究以及依据光束的传输矩阵,分析了双激光晶体热透镜效应对于谐振腔稳定性的影响,设计了双端抽运双激光晶体折叠腔。在双端抽运双Nd:YVO4绿光激光器系统中,LBO晶体采用了Ⅰ类非临界相位匹配腔内倍频方式,当抽运光功率为26.56W时,获得了5.5 W的稳定连续绿光输出,其光-光转换效率为20.7%。结果同时表明,在谐振腔内插入双激光增益介质,不仅可以提高激光器的光-光转换效率,而且两个激光晶体热透镜效应相互作用的结果可以增强谐振腔的稳定性。
    Abstract: In order to improve the output power and the optical-optical conversion efficiency of a laser diode pumped all-solid-state laser,a double Nd:YVO4 crystals green laser was designed.Through investigation of temperature field distribution in laser crystal and based on the transmission matrixes,the stable condition of cavity influenced by the thermal lens effects of double laser crystals was analyzed and a folded cavity of double-end-pumped double Nd:YVO4 crystals was introduced.In double-ends-pumped double Nd:YVO4 crystals green laser system,Ⅰ-type noncritical phase matching LBO crystal was used as intracavity doubling frequency.When the pump power of two diode lasers was 26.56W,the 5.5W CW 532nm green laser was got and the optical-optical conversion efficiency reached up to 20.7%.The result shows that the double laser gain mediums inserted in cavity can not only improve the optical-optical conversion efficiency of laser,but also enhance the resonant stability through the interaction of two laser crystals' thermal lens effect.
