本文报道了Nd：YAG晶体从室温到液氮温度范围内吸收截面的详细光谱特性。利用这种带内抽运方案，研制了一种新型的工作在869 nm的体布拉格光栅锁定二极管激光器阵列（DLA），用于端面抽运低温冷却的Nd：YAG晶体。其结果是，第一个60瓦低温冷却Nd：YAG激光器工作在946 nm的斜率，光-光，效率。
Detailed spectroscopic characterisation of theabsorption cross section of Nd:YAG at temperatures ranging from room temperature to liquid nitrogen temperature is reported. Exploiting this in-band pumping scheme, a novel volume-Bragg-grating-locked diode-laser array (DLA) operating at 869 nm was developed to end-pump a cryogenically cooled Nd:YAG crystal. As a result, the first 60-W cryogenically-cooled Nd:YAG laser operating at 946 nm is demonstrated with a slope, and optical-to-optical, efficiency of.
