摘要
为有效抑制1064nm和1338nm谱线振荡,采用三色镜技术,实现了Nd∶YAG单一谱线1318.8nm激光准连续运转,抽运功率为2100W时,激光输出功率为122W,电光转换效率为5.8%,斜率效率为8.22%,激光输出功率不稳定度≤±5%,激光阈值功率约为500W。该激光系统结构简单,工作稳定,在激光医疗、国防安全等领域具有应用价值。
To suppress 1064nm line and 1338nm line,utilizing the dichroic mirror technology,a Nd∶YAG quasi-CW laser operating at t he single wavelength of 1318.8nm was developed.The output power of 122W was obta ined at a pump power of 2100W with the total efficiency of 5.8%,and the slope e fficiency of 8.22%.The unstability of output power was less than (±5%.)The th reshold power was about 500W.The 1318.8nm Nd∶YAG laser with simple c onstruction can work stably,which is of great value to laser therapy and nation al defence.
