报道了一种具有有序石榴石结构的新型激光晶体Lu3Sc2Ga3O12：Nd3+。用半导体激光器和氙灯室温泵浦，激发了1.0622μm波长(4F3/2、4I11/2产生通道)的受激辐射。对于Nd3+离子掺杂晶体的远景光谱和激光研究，详细计算了能量最大的所有4F3流形间J J‘跃迁的全套平方约化矩阵元，直到约67000 cm−1。
A new laser crystal Lu3Sc2Ga3O12:Nd3+ with ordered garnet structure is developed. Its stimulated emission at 1.0622 μm wavelength (4F3/2 4I11/2 generating channel) with laser-diode and Xe-flashlamp pumping at room temperature is excited. For prospecting spectroscopic and laser investigations with Nd3+ -ion doped crystals the detailed calculations of the full set of squared reduced-matrix elements for all 4f3 intermanifold J J′ transitions with maximal energy till about 67000 cm−1 are performed.
