Research on optical, thermomechanical and laser properties of Cr, Nd：ZW crystal

摘要: 生长出Cr3+,Nd3+:ZnWO4(Cr,Nd:ZW)单晶,尺寸为25mm×50mm,研究了Cr,Nd:ZW晶体的光学性质、热学性质,测定了其吸收和发射截面,激发态寿命和激光性能.结果表明,双掺有效地改善了激光性能,室温下获得0.95μm单脉冲激光能量输出1.62mJ,斜效率为0.79%.

Abstract: The Cr3+,Nd3+:ZnWO4(Cr,Nd:ZW)single crystals to size of 25mm×50mm have been grown by CZ method in our laboratory.The optical and thermomechanical properties such as the absorption section,emission section,life of excitation state,laser action,are experimentally investigated.The results show that the Cr,Nd:ZW laser can operate at 950nm with 1.62mJ/pulse output energy and 0.79% slope efficiency obtained at room temperature.
