这项工作首次报道了室温下 1.3 μm 左右的 Nd3+ 掺杂 LiNbO3:ZnO 中的连续波激光作用。光谱学已被用来确定4F3/2→4I13/2通道的主要激光特性，例如激光波长处的发射截面和激发态吸收截面。内部光损耗是通过激光增益实验估计的。在非最佳条件下，激光斜率效率可达 30%。
This work reports for the first time continuous-wave laser action at room temperature around 1.3 μm in Nd3+doped LiNbO3:ZnO. Optical spectroscopy has been used to determine the main laser characteristics of4F3/2?4I13/2channel, such as emission cross section and excited-state absorption cross section at laser wavelengths. Internal optical losses have been estimated from laser gain experiments. Under non-optimal conditions laser slope efficiencies of 30% have been obtained.
