测量了Er：LiNbOs单晶体4113/2-4115/2跃迁（A ~ 1.5 μ m）的偏振相关吸收和发射光谱。低温（10 K）的斯塔克分裂能级的这两个歧管的测量表明至少有两个Er 3+网站。应用McCumber理论来确定Er：LiNb 〇 3的吸收和发射截面。这些值被用来计算Er：LiNbOs沟道波导的增益特性。计算表明，在几厘米长的波导中，使用~ 20 mW的泵浦功率可获得10 dB的增益。
The polarization-dependent absorption and emission spectra of the 4113/2-4115/2 transition (A - 1.5 pm) in single crystal bulk Er:LiNbOs have been measured. Low-temperature (10 K) measurements of the Stark split energy levels of these two manifolds indicate at least two Er3+ sites. McCumber theory is applied to determine the Er:LiNb03 absorption and emission cross sections. These values are used to calculate the gain charac- teristics of Er:LiNbOs channel waveguides. Calculations indicate that a gain of 10 dB is achievable in a waveguide of several centimeters using -20-mW pump power.
