用质子交换法制备了Nd:MgO:LiNbO3波导。通过测量平面波导的二次离子质谱,得到了波导的原子组分分布,并测量了Nd:MgO:LiNbO3晶体的吸收谱线,最后利用端面耦合,分别得到了条波导内和衬底内激光诱导的荧光谱线。

Nd:MgO:LiNbO3 waveguides have been fabricated by proton-exchange method. To obtain the atomic composition profiles of the waveguide, the SIMS (second ion mass spectrum) of the planer waveguide was measured. The absorption spectra of Nd:MgO:LiNbO3 crystal and the fluorescence spectra induced in the channel waveguide and subetrate were measured respectively.
