A High-Power Continuous-Wave Laser-Diode End-Pumped Nd:YVO4 Laser of Single-Frequency Operation 下载免费PDF全文
We design and build a cw high quality and high power Nd:YV04 laser of single frequencv operation with a laser-diode dual-end-pumped geometry. The influence of the Nd^3 -doping concentration in the Nd:YVO4 crystal on the output performance of laser is theoretically and experimentally studied. With a Nd:YVO4 crystal of the Nd^3 -doping concentration 0.3 at. % and at pump power of 45 W, the output power of the single frequency laser is 18 W, and the slope efficiency is 48%. 相似文献

波罗棱镜谐振腔激光器具有机械稳定度高、光束质量好的特点。波罗棱镜会使入射光退偏,调Q时1/4λ波片无法有效工作,需要使用适当的波片补偿。利用琼斯矩阵建立波罗棱镜谐振腔调Q的数学模型并进行求解计算。分析了不同波罗棱镜方位角下的最优补偿波片并计算了波片公差、波罗棱镜折射率公差、方位角安装公差等对消光比的影响。当波罗棱镜水平放置,波片相位公差±0.02λ,关门消光比大于20 dB;波罗棱镜45°/135°放置时,存在四种对应的最优关门波片,波罗棱镜方位角0±4.66°的范围内,关门消光比可大于30 d B。以上结果为波罗棱镜谐振腔调Q激光器的设计提供更优及更具工程化意义的依据。 相似文献
