研制了一台高平均功率传导冷却二极管泵浦Nd：YLF棒形激光器。采用了一种新的固体棱镜泵浦光约束腔的传导冷却侧面泵浦方案。采用透明、高热导率的MgF2棱镜作为高效率的泵浦腔和低热阻的散热器。腔的泵浦效率和热阻分别为85%和0.20摄氏度W。当该方案与热管散热相结合时，最大平均输出功率为72 W，光学斜率效率高达49%。
A high-average-power conduction-cooled diode-pumped Nd:YLF rod laser has been developed. A new conduction-cooled side-pumping scheme with a solid prismatic pump-light confinement cavity was employed. A transparent, high-thermal-conductivity MgF>(2) prism was used as a highly efficient pump cavity as well as a low-thermal-resistance heat spreader. The pumping efficiency and thermal resistance of the cavity were 85% and 0.20 degrees C degrees W, respectively. When this scheme was combined with heat pipes for heat removal, a maximum average output power of 72 W was demonstrated, with an optical slope efficiency as high as 49%.
